A Z’-factor > 0 is potentially + screenable; a Z’-factor > 0.5 is considered an excellent assay. + The formula is 1 - 3 × (σ\ :sub:`p` + + σ\ :sub:`n`)/\|μ\ :sub:`p` - μ\ :sub:`n`\ \| where σ\ :sub:`p` and + σ\ :sub:`n` are the standard deviations of the positive and + negative controls, and μ\ :sub:`p` and μ\ :sub:`n` are the means + of the positive and negative controls. + - *Vfactor:* The V-factor is a generalization of the Z’-factor, and + is calculated as 1 - 6 × mean(σ)/\|μ\ :sub:`p` - + μ\ :sub:`n`\ \| where σ are the standard deviations of the data, + and μ\ :sub:`p` and μ\ :sub:`n` are defined as above. + - *EC50:* The half maximal effective concentration (EC50) is the + concentration of a treatment required to induce a response that + is 50% of the maximal response. + - *OneTailedZfactor:* This measure is an attempt to overcome a + limitation of the original Z’-factor formulation (it assumes a + Gaussian distribution) and is informative for populations with + moderate or high amounts of skewness. In these cases, long tails + opposite to the mid-range point lead to a high standard deviation + for either population, which results in a low Z’ factor even + though the population means and samples between the means may be + well-separated. Therefore, the one-tailed Z’ factor is calculated + with the same formula but using only those samples that lie + between the positive/negative population means. **This is not yet + a well established measure of assay robustness, and should be + considered experimental.** + +For both Z’ and V factors, the highest possible value (best assay +quality) is 1, and they can range into negative values (for assays where +distinguishing between positive and negative controls is difficult or +impossible). The Z’ factor is based only on positive and negative +controls. The V factor is based on an entire dose-response curve rather +than on the minimum and maximum responses. When there are only two doses +in the assay (positive and negative controls only), the V factor will +equal the Z’ factor. + +Note that if the standard deviation of a measured feature is zero for a +particular set of samples (e.g., all the positive controls), the Z’ and +V factors will equal 1 despite the fact that the assay quality is poor. +This can occur when there is only one sample at each dose. This also +occurs for some non-informative measured features, like the number of +cytoplasm compartments per cell, which is always equal to 1. + +This module can create MATLAB scripts that display the EC50 curves for +each measurement. These scripts will require MATLAB and the statistics +toolbox in order to run. See *Create dose-response plots?* below. + +References +^^^^^^^^^^ + +- *Z’ factor:* Zhang JH, Chung TD, et al.

It reports how many objects fall into each class as +well as the percentage of objects that fall into each class. The module +asks you to select the measurement feature to be used to classify your +objects and specify the bins to use. It also requires you to have run +a measurement or **CalculateMath** previous to this module in the +pipeline so that the measurement values can be used to classify the +objects. + +There are two flavors of measurement-based classification: + +- The first classifies each object according to the measurements you + choose and assigns each object to one class per measurement. You may + specify more than two classification bins per measurement. +- The second classifies each object according to two measurements and + two threshold values. The module classifies each object once per + measurement resulting in four possible object classes. The module + then stores one measurement per object, based on the object’s class. + +Note that objects without a measurement are not counted as belonging in +a classification bin and will not show up in the output image (shown in +the module display window); in the object classification they will have +a value of False for all bins. However, they are still counted in the +total number of objects and hence are reflected in the classification +percentages. + +In **model** mode, this module will classify objects into distinct classes +as determined by the machine learning model the user supplies. Models +can be trained and exported using the Classifier tool in CellProfiler +Analyst. Only models trained in CellProfiler Analyst 3.0+ will be +compatible.

If you are using *Each* mode, +smoothing is definitely needed. For *All* modes, you usually also want to +smooth, especially if you have few objects in each image or a small image set. + +You should smooth to the point where the illumination function resembles +a believable pattern. For example, if you are trying to correct a lamp +illumination problem, apply smoothing until you obtain a fairly smooth +pattern without sharp bright or dim regions.

The *%(SM_GAUSSIAN_FILTER)s* convolves the image with a + Gaussian whose full width at half maximum is the artifact diameter + entered. Its effect is to blur and obscure features smaller than the + specified diameter and spread bright or dim features larger than the + specified diameter. The *%(SM_MEDIAN_FILTER)s* finds the median pixel value within + the diameter you specify. It removes bright or dim features + that are significantly smaller than the specified diameter. +- *%(SM_TO_AVERAGE)s:* A less commonly used option is to completely + smooth the entire image, which will create a flat, smooth image where + every pixel of the image is the average of what the illumination + function would otherwise have been. +- *%(SM_SPLINES)s:* This method (*Lindblad and Bengtsson, 2001*) fits + a grid of cubic splines to the background while excluding foreground + pixels from the calculation.

Note that the computation time can + be significant, especially with a large number of control points. +- *%(SM_CONVEX_HULL)s:* This method can be used on an image whose objects are + darker than their background and whose illumination intensity + decreases monotonically from the brightest point.

If this one-to-one correspondence is *not* the case for +all objects in the pipeline (for example, if dozens of speckles are +identified and measured for each nucleus), then you must configure +**ExportToDatabase** to export only objects that maintain the one-to-one +correspondence (for example, export only *Nucleus* and *Cytoplasm*, but +omit *Speckles*). If you have extracted “Plate” and “Well” metadata from +image filenames or loaded “Plate” and “Well” metadata via the +**Metadata** or **LoadData** modules, you can ask CellProfiler to create +a “Per\_Well” table, which aggregates object measurements across wells. +This option will output a SQL file (regardless of whether you choose to +write directly to the database) that can be used to create the Per\_Well +table. **Note** that the “Per\_Well” mean/median/stdev values are only usable +for database type MySQL, not SQLite. + +At the secure shell where you normally log in to MySQL, type the +following, replacing the italics with references to your database and +files, to import these CellProfiler measurements to your database: + +``mysql -h hostname -u username -p databasename < pathtoimages/perwellsetupfile.SQL`` + +The commands written by CellProfiler to create the Per\_Well table will +be executed. Oracle is not fully supported at present; you can create +your own Oracle DB using the .csv output option and writing a simple +script to upload to the database. + +For details on the nomenclature used by CellProfiler for the exported +measurements, see *Help > General Help > How Measurements Are Named*. + +| + +============ ============ =============== +Supports 2D?

You can +do this by specifying metadata tags for the folder name and file name: + +- Choose "*Elsewhere…*" or "*Default Input/Output Folder sub-folder*" for + the output file location. Do note that regardless of your choice, + the Experiment.csv is saved to the Default Input/Output Folder and + *not* to individual subfolders. All other per-image and per-object + .csv files are saved to the appropriate subfolders. + See `Github issue #1110 `__ + for details. + +- Insert the metadata tag of choice into the output path. You can + insert a previously defined metadata tag by either using: + + - The insert key + - A right mouse button click inside the control + - In Windows, the Context menu key, which is between the Windows key + and Ctrl key + + The inserted metadata tag will appear in green. To change a + previously inserted metadata tag, navigate the cursor to just before + the tag and either: + + - Use the up and down arrows to cycle through possible values. + - Right-click on the tag to display and select the available values. + + In this instance, you would select the metadata tag “Treatment1” +- Uncheck "*Export all measurements?*" +- Uncheck "*Use the object name for the file name?*" +- Using the same approach as above, select the metadata tag + “Treatment2”, and complete the filename by appending the text “.csv”. + +| Here’s an example table of the files that would be generated: + ++--------------+--------------+---------------------------+ +| Treatment1 | Treatment2 | Path | ++==============+==============+===========================+ +| 1M\_NaCl | 20uM\_DMSO | 1M\_NaCl/20uM\_DMSO.csv | ++--------------+--------------+---------------------------+ +| 1M\_NaCl | 40uM\_DMSO | 1M\_NaCl/40uM\_DMSO.csv | ++--------------+--------------+---------------------------+ +| 2M\_NaCl | 20uM\_DMSO | 2M\_NaCl/20uM\_DMSO.csv | ++--------------+--------------+---------------------------+ +| 2M\_NaCl | 40uM\_DMSO | 2M\_NaCl/40uM\_DMSO.csv | ++--------------+--------------+---------------------------+ + +Measurements made by this module +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +For details on the nomenclature used by CellProfiler for the exported +measurements, see *Help > General Help > How Measurements Are Named*. +See also +^^^^^^^^ + +See also **ExportToDatabase**. +""" + +import base64 +import csv +import logging +import os + +import numpy +from cellprofiler_core.constants.image import C_MD5_DIGEST, C_SCALING, C_HEIGHT, C_WIDTH +from cellprofiler_core.constants.measurement import ( + EXPERIMENT, + IMAGE, + AGG_MEAN, + AGG_MEDIAN, + AGG_STD_DEV, + C_URL, + C_PATH_NAME, + C_FILE_NAME, + NEIGHBORS, + R_FIRST_IMAGE_NUMBER, + R_SECOND_IMAGE_NUMBER, + R_FIRST_OBJECT_NUMBER, + R_SECOND_OBJECT_NUMBER, +) +from cellprofiler_core.constants.module import ( + IO_FOLDER_CHOICE_HELP_TEXT, + IO_WITH_METADATA_HELP_TEXT, + USING_METADATA_HELP_REF, + USING_METADATA_TAGS_REF, +) +from cellprofiler_core.constants.pipeline import EXIT_STATUS +from cellprofiler_core.measurement import Measurements +from cellprofiler_core.module import Module +from cellprofiler_core.preferences import ABSOLUTE_FOLDER_NAME +from cellprofiler_core.preferences import DEFAULT_INPUT_FOLDER_NAME +from cellprofiler_core.preferences import DEFAULT_INPUT_SUBFOLDER_NAME +from cellprofiler_core.preferences import DEFAULT_OUTPUT_FOLDER_NAME +from cellprofiler_core.preferences import DEFAULT_OUTPUT_SUBFOLDER_NAME +from cellprofiler_core.preferences import get_headless +from cellprofiler_core.setting import Binary +from cellprofiler_core.setting import Divider +from cellprofiler_core.setting import Measurement +from cellprofiler_core.setting import SettingsGroup +from cellprofiler_core.setting import ValidationError +from cellprofiler_core.setting.choice import CustomChoice, Choice +from cellprofiler_core.setting.do_something import DoSomething, RemoveSettingButton +from cellprofiler_core.setting.multichoice import MeasurementMultiChoice +from cellprofiler_core.setting.subscriber import ImageSubscriber, LabelSubscriber +from cellprofiler_core.setting.text import Directory, Text +from cellprofiler_core.utilities.core.modules.load_data import ( + is_file_name_feature, + is_path_name_feature, +) +from cellprofiler_core.utilities.measurement import ( + find_metadata_tokens, + get_agg_measurement_name, +) + +from cellprofiler.gui.help.content import MEASUREMENT_NAMING_HELP + +LOGGER = logging.getLogger(__name__) + +MAX_EXCEL_COLUMNS = 256 +MAX_EXCEL_ROWS = 65536 + +DELIMITER_TAB = "Tab" +DELIMITER_COMMA = 'Comma (",")' +DELIMITERS = (DELIMITER_COMMA, DELIMITER_TAB) + +OBJECT_RELATIONSHIPS = "Object relationships" +RELATIONSHIPS = "Relationships" + +SETTING_OG_OFFSET_V7 = 15 +SETTING_OG_OFFSET_V8 = 16 +SETTING_OG_OFFSET_V9 = 15 +SETTING_OG_OFFSET_V10 = 17 +SETTING_OG_OFFSET_V11 = 18 +"""Offset of the first object group in the settings""" +SETTING_OG_OFFSET = 18 + +"""Offset of the object name setting within an object group""" +SETTING_OBJECT_NAME_IDX = 0 + +"""Offset of the previous file flag setting within an object group""" +SETTING_PREVIOUS_FILE_IDX = 1 + +"""Offset of the file name setting within an object group""" +SETTING_FILE_NAME_IDX = 2 + +SETTING_AUTOMATIC_FILE_NAME_IDX = 3 + +"""# of settings within an object group""" +SETTING_OBJECT_GROUP_CT = 4 + +"""The caption for the image set number""" +IMAGE_NUMBER = "ImageNumber" + +"""The caption for the object #

This module identifies +dead worms by fitting a straight shape to a binary image at many +different angles to identify the regions where the shape could fit. Each +placement point has a x and y location and an angle associated with the +fitted shape’s placement. Conceptually, these can be visualized in three +dimensions with the z direction being the angle (and with the angle, 0, +being adjacent to the largest angle as well as the smallest angle +greater than zero). The module labels the resulting 3-D volume. It +records the X, Y and angle of the centers of each of the found objects +and creates objects by collapsing the 3-D volume to 2-D. These objects +can then be used as seeds for **IdentifySecondaryObjects**. + +**IdentifyDeadWorms** fits a diamond shape to the image. The shape is +defined by its width and length. The length is the distance in pixels +along the long axis of the diamond and should be less than the length of +the shortest dead worm to be detected. The width is the distance in +pixels along the short axis of the diamond and should be less than the +width of the worm. + +| + +============ ============ =============== +Supports 2D? Supports 3D?

For example: + +- The nuclei of cells are usually more easily identifiable than whole- + cell stains due to their + more uniform morphology, high contrast relative to the background + when stained, and good separation between adjacent nuclei. These + qualities typically make them appropriate candidates for primary + object identification. +- In contrast, whole-cell stains often yield irregular intensity patterns + and are lower-contrast with more diffuse staining, making them more + challenging to identify than nuclei without some supplemental image + information being provided. In addition, cells often touch or even overlap + their neighbors making it harder to delineate the cell borders. For + these reasons, cell bodies are better suited for *secondary object* + identification, because they are best identified by using a + previously-identified primary object (i.e, the nuclei) as a + reference. See the **IdentifySecondaryObjects** module for details on + how to do this. + +What do I need as input? +^^^^^^^^^^^^^^^^^^^^^^^^ + +To use this module, you will need to make sure that your input image has +the following qualities: + +- The image should be grayscale. +- The foreground (i.e, regions of interest) are lighter than the + background. +- The image should be 2D. 2D slices of 3D images are acceptable if the + image has not been loaded as volumetric in the **NamesAndTypes** + module. For volumetric analysis + of 3D images, please see the **Watershed** module. + +If this is not the case, other modules can be used to pre-process the +images to ensure they are in the proper form: + +- If the objects in your images are dark on a light background, you + should invert the images using the Invert operation in the + **ImageMath** module. +- If you are working with color images, they must first be converted to + grayscale using the **ColorToGray** module. +- If your images are brightfield/phase/DIC, they may be processed with the + **EnhanceOrSuppressFeatures** module with its "*Texture*" or "*DIC*" settings. +- If you struggle to find effective settings for this module, you may + want to check our `tutorial`_ on preprocessing these images with + ilastik prior to using them in CellProfiler. + +What are the advanced settings? +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +**IdentifyPrimaryObjects** allows you to tweak your settings in many ways; +so many that it can often become confusing where you should start. This is +typically the most important but complex step in creating a good pipeline, +so do not be discouraged: other modules are easier to configure! +Using **IdentifyPrimaryObjects** with *'Use advanced settings?'* set to *'No'* +allows you to quickly try to identify your objects based only their typical size; +CellProfiler will then use its built-in defaults to decide how to set the +threshold and how to break clumped objects apart. If you are happy with the +results produced by the default settings, you can then move on to +construct the rest of your pipeline; if not, you can set +*'Use advanced settings?'* to *'Yes'* which will allow you to fully tweak and +customize all the settings. + +What do I get as output? +^^^^^^^^^^^^^^^^^^^^^^^^ + +A set of primary objects are produced by this module, which can be used +in downstream modules for measurement purposes or other operations. See +the section "Measurements made by this module" below +for the measurements that are produced directly by this module. Once the module +has finished processing, the module display window will show the +following panels: + +- *Upper left:* The raw, original image. +- *Upper right:* The identified objects shown as a color image where + connected pixels that belong to the same object are assigned the same + color (*label image*). Note that assigned colors + are arbitrary; they are used simply to help you distinguish the + various objects. +- *Lower left:* The raw image overlaid with the colored outlines of the + identified objects. Each object is assigned one of three (default) + colors: + + - Green: Acceptable; passed all criteria + - Magenta: Discarded based on size + - Yellow: Discarded due to touching the border + + If you need to change the color defaults, you can make adjustments in + *File > Preferences*. +- *Lower right:* A table showing some of the settings used by the module + in order to produce the objects shown. Some of these are as you + specified in settings; others are calculated by the module itself. + +{HELP_ON_SAVING_OBJECTS} + +Measurements made by this module +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +**Image measurements:** + +- *Count:* The number of primary objects identified. +- *OriginalThreshold:* The global threshold for the image. +- *FinalThreshold:* For the global threshold methods, this value is the + same as *OriginalThreshold*. For the adaptive or per-object methods, + this value is the mean of the local thresholds. +- *WeightedVariance:* The sum of the log-transformed variances of the + foreground and background pixels, weighted by the number of pixels in + each distribution. +- *SumOfEntropies:* The sum of entropies computed from the foreground + and background distributions. + +**Object measurements:** + +- *Location\_X, Location\_Y:* The pixel (X,Y) coordinates of the + primary object centroids. The centroid is calculated as the center of + mass of the binary representation of the object. + +Technical notes +^^^^^^^^^^^^^^^ + +CellProfiler contains a modular three-step strategy to identify objects +even if they touch each other ("declumping"). It is based on previously +published +algorithms (*Malpica et al., 1997; Meyer and Beucher, 1990; Ortiz de +Solorzano et al., 1999; Wahlby, 2003; Wahlby et al., 2004*). Choosing +different options for each of these three steps allows CellProfiler to +flexibly analyze a variety of different types of objects. The module has +many options, which vary in terms of speed and sophistication. More +detail can be found in the Settings section below. Here are the three +steps, using an example where nuclei are the primary objects: + +#. CellProfiler determines whether a foreground region is an individual + nucleus or two or more clumped nuclei. +#. The edges of nuclei are identified, using thresholding if the object + is a single, isolated nucleus, and using more advanced options if the + object is actually two or more nuclei that touch each other. +#. Some identified objects are discarded or merged together if they fail + to meet certain your specified criteria. For example, partial objects + at the border of the image can be discarded, and small objects can be + discarded or merged with nearby larger ones. A separate module, + **FilterObjects**, can further refine the identified nuclei, if + desired, by excluding objects that are a particular size, shape, + intensity, or texture. + +References +^^^^^^^^^^ + +- Malpica N, de Solorzano CO, Vaquero JJ, Santos, A, Vallcorba I, + Garcia-Sagredo JM, del Pozo F (1997) “Applying watershed algorithms + to the segmentation of clustered nuclei.” *Cytometry* 28, 289-297. + (`link`_) +- Meyer F, Beucher S (1990) “Morphological segmentation.” *J Visual + Communication and Image Representation* 1, 21-46. + (`link `__) +- Ortiz de Solorzano C, Rodriguez EG, Jones A, Pinkel D, Gray JW, Sudar + D, Lockett SJ.

In addition, cells often +touch their neighbors making it harder to delineate the cell borders. It +is often easier to identify an organelle which is well separated +spatially (such as the nucleus) as an object first and then use that +object to guide the detection of the cell borders. See the +**IdentifyPrimaryObjects** module for details on how to identify a +primary object. + +In order to identify the edges of secondary objects, this module +performs two tasks: + +#. Finds the dividing lines between secondary objects that touch each + other. +#. Finds the dividing lines between the secondary objects and the + background of the image. In most cases, this is done by thresholding + the image stained for the secondary objects. + +What do I need as input? +^^^^^^^^^^^^^^^^^^^^^^^^ + +This module identifies secondary objects based on two types of input: + +#. An *object* (e.g., nuclei) identified from a prior module. These are + typically produced by an **IdentifyPrimaryObjects** module, but any + object produced by another module may be selected for this purpose. +#. (*optional*) An *image* highlighting the image features defining the edges of the + secondary objects (e.g., cell edges). + This is typically a fluorescent stain for the cell body, membrane or + cytoskeleton (e.g., phalloidin staining for actin). However, any + image that produces these features can be used for this purpose. For + example, an image processing module might be used to transform a + brightfield image into one that captures the characteristics of a + cell body fluorescent stain. This input is optional because you can + instead define secondary objects as a fixed distance around each + primary object. + +What do I get as output? +^^^^^^^^^^^^^^^^^^^^^^^^ + +A set of secondary objects are produced by this module, which can be +used in downstream modules for measurement purposes or other operations. +Because each primary object is used as the starting point for producing +a corresponding secondary object, keep in mind the following points: + +- The primary object will always be completely contained within a + secondary object. For example, nuclei are completely enclosed within + cells identified by actin staining. +- There will always be at most one secondary object for each primary + object. + +Once the module has finished processing, the module display window will +show the following panels; +note that these are just for display: you must use the **SaveImages** +module if you would like to save any of these images to the hard drive +(as well, the **OverlayOutlines** module or **ConvertObjectsToImage** +modules might be needed): + +- *Upper left:* The raw, original image. +- *Upper right:* The identified objects shown as a color image where + connected pixels that belong to the same object are assigned the same + color (*label image*).

This method is considered an improvement on the + traditional *Watershed* method. The dividing lines between objects + are determined by a combination of the distance to the nearest + primary object and intensity gradients. This algorithm uses local + image similarity to guide the location of boundaries between cells. + Boundaries are preferentially placed where the image’s local + appearance changes perpendicularly to the boundary (*Jones et al, + 2005*). + + |image0| The {M_PROPAGATION:s} algorithm is the default approach for secondary object + creation. Each primary object is a "seed" for its corresponding + secondary object, guided by the input + image and limited to the foreground region as determined by the chosen + thresholding method. λ is a regularization parameter; see the help for + the setting for more details. Propagation of secondary object labels is + by the shortest path to an adjacent primary object from the starting + (“seeding”) primary object.

In this variant, the watershed + algorithm operates on the Sobel transformed image which computes an + intensity gradient. This method works best when the image intensity + drops off or increases rapidly near the boundary between cells. +- *{M_WATERSHED_I:s}:* This method is similar to the above, but it + uses the inverted intensity of the image for the watershed. The areas + of lowest intensity will be detected as the boundaries between cells. This + method works best when there is a saddle of relatively low intensity + at the cell-cell boundary. +- *Distance:* In this method, the edges of the primary objects are + expanded a specified distance to create the secondary objects. For + example, if nuclei are labeled but there is no stain to help locate + cell edges, the nuclei can simply be expanded in order to estimate + the cell’s location. This is often called the “doughnut” or “annulus” + or “ring” approach for identifying the cytoplasm. There are two + methods that can be used: + + - *{M_DISTANCE_N:s}*: In this method, the image of the secondary + staining is not used at all; the expanded objects are the final + secondary objects. + - *{M_DISTANCE_B:s}*: Thresholding of the secondary staining image + is used to eliminate background regions from the secondary + objects. This allows the extent of the secondary objects to be + limited to a certain distance away from the edge of the primary + objects without including regions of background. + +References +^^^^^^^^^^ + +Jones TR, Carpenter AE, Golland P (2005) “Voronoi-Based Segmentation of +Cells on Image Manifolds”, *ICCV Workshop on Computer Vision for +Biomedical Image Applications*, 535-543.

Use the +**IdentifyTertiaryObjects** module to define the +cytoplasm, the region outside the nucleus but within the cell body, as a +new object which can be measured in downstream **Measure** modules. + +What do I need as input? +^^^^^^^^^^^^^^^^^^^^^^^^ + +This module will take the smaller identified objects and remove them +from the larger identified objects. For example, “subtracting” the +nuclei from the cells will leave just the cytoplasm, the properties of +which can then be measured by downstream **Measure** modules. The larger +objects should therefore be equal in size or larger than the smaller +objects and must completely contain the smaller objects; +**IdentifySecondaryObjects** will produce objects that satisfy this +constraint. Ideally, both inputs should be objects produced by prior +**Identify** modules. + +What do I get as output? +^^^^^^^^^^^^^^^^^^^^^^^^ + +A set of objects are produced by this module, which can be used +in downstream modules for measurement purposes or other operations. +Because each tertiary object is produced from primary and secondary +objects, there will always be at most one tertiary object for each +larger object. See the section "Measurements made by this module" below for +the measurements that are produced by this module. + +Note that if the smaller objects are not completely contained within the +larger objects, creating subregions using this module can result in objects +with a single label (that is, identity) that nonetheless are not contiguous. +This may lead to unexpected results when running measurement modules such as +**MeasureObjectSizeShape** because calculations of the perimeter, aspect +ratio, solidity, etc. typically make sense only for contiguous objects. +Other modules, such as **MeasureImageIntensity**, are not affected and +will yield expected results. + +{HELP_ON_SAVING_OBJECTS} + +Measurements made by this module +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +**Image measurements:** + +- *Count:* The number of tertiary objects identified. + +**Object measurements:** + +- *Parent:* The identity of the primary object and secondary object + associated with each tertiary object. + +- *Location\_X, Location\_Y:* The pixel (X,Y) coordinates of the center + of mass of the identified tertiary objects. + +""".format( + **{ + "DEFINITION_OBJECT": _help.DEFINITION_OBJECT, + "HELP_ON_SAVING_OBJECTS": _help.HELP_ON_SAVING_OBJECTS, + } +) + +"""The parent object relationship points to the secondary / larger objects""" +R_PARENT = "Parent" +"""The removed object relationship points to the primary / smaller objects""" +R_REMOVED = "Removed" + + +class IdentifyTertiaryObjects(Module): + module_name = "IdentifyTertiaryObjects" + variable_revision_number = 3 + category = "Object Processing" + + def create_settings(self): + """Create the settings for the module + + Create the settings for the module during initialization. + """ + self.secondary_objects_name = LabelSubscriber( + "Select the larger identified objects", + "None", + doc="""\ +Select the larger identified objects.

For a pair of + images R and G, the overlap coefficient is measured as r = sum(Ri \* + Gi) / sqrt (sum(Ri\*Ri)\*sum(Gi\*Gi)). +- *Manders coefficient:* The Manders coefficient for a pair of images R + and G is measured as M1 = sum(Ri_coloc)/sum(Ri) and M2 = + sum(Gi_coloc)/sum(Gi), where Ri_coloc = Ri when Gi > 0, 0 otherwise + and Gi_coloc = Gi when Ri >0, 0 otherwise. +- *Manders coefficient (Costes Automated Threshold):* Costes’ automated + threshold estimates maximum threshold of intensity for each image + based on correlation. Manders coefficient is applied on thresholded + images as Ri_coloc = Ri when Gi > Gthr and Gi_coloc = Gi when Ri > + Rthr where Gthr and Rthr are thresholds calculated using Costes’ + automated threshold method. +- *Rank Weighted Colocalization coefficient:* The RWC coefficient for a + pair of images R and G is measured as RWC1 = + sum(Ri_coloc\*Wi)/sum(Ri) and RWC2 = sum(Gi_coloc\*Wi)/sum(Gi), + where Wi is Weight defined as Wi = (Rmax - Di)/Rmax where Rmax is the + maximum of Ranks among R and G based on the max intensity, and Di = + abs(Rank(Ri) - Rank(Gi)) (absolute difference in ranks between R and + G) and Ri_coloc = Ri when Gi > 0, 0 otherwise and Gi_coloc = Gi + when Ri >0, 0 otherwise.

indicating possible image +aberrations, e.g., blur (poor focus), intensity, saturation (i.e., the +percentage of pixels in the image that are at/near the maximum possible +value, and at/near the minimum possible value). Details +and guidance for each of these measures is provided in the settings +help. + +Please note that for best results, this module should be applied to the +original raw images, rather than images that have already been +corrected for illumination. + +| + +============ ============ =============== +Supports 2D? Supports 3D? Respects masks? +============ ============ =============== +YES YES YES +============ ============ =============== + +Measurements made by this module +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +- **Blur metrics** + + - *FocusScore:* A measure of the intensity variance across the + image. This score is calculated using a normalized + variance, which was the best-ranking algorithm for brightfield, phase + contrast, and DIC images (*Sun, 2004*). Higher focus scores + correspond to lower bluriness. + More specifically, the focus score computes the intensity variance of + the entire image divided by mean image intensity. Since it is + tailored for autofocusing applications (difference focus for the same + field of view), it assumes that the overall intensity and the number + of objects in the image is constant, making it less useful for + comparison images of different fields of view. For distinguishing + extremely blurry images, however, it performs well. + - *LocalFocusScore:* A measure of the intensity variance between + image sub-regions. A local version of the Focus Score, it + subdivides the image into non-overlapping tiles, computes the + normalized variance for each, and takes the mean of these values as + the final metric. It is potentially more useful for comparing focus + between images of different fields of view, but is subject to the + same caveats as the Focus Score. It can be useful in differentiating + good versus badly segmented images in the cases when badly segmented + images usually contain no cell objects with high background noise. + - *Correlation:* A measure of the correlation of the image for a + given spatial scale. This is a measure of the image spatial + intensity distribution computed across sub-regions of an image for a + given spatial scale (*Haralick, 1973*). If an image is blurred, the + correlation between neighboring pixels becomes high, producing a high + correlation value. A similar approach was found to give optimal + performance for fluorescence microscopy applications (*Vollath, + 1987*). + Some care is required in selecting an appropriate spatial scale + because differences in the spatial scale capture various features: + moderate scales capture the blurring of intracellular features better + than small scales and larger scales are more likely to reflect + cell confluence than focal blur. You should select a spatial scale + no bigger than the objects of interest, although you can select + as many scales as desired and check empirically which is best. + - *PowerLogLogSlope:* The slope of the image log-log power spectrum. + The power spectrum contains the frequency information of the image, + and the slope gives a measure of image blur. A higher slope + indicates more lower frequency components, and hence more blur + (*Field, 1997*). This metric is recommended for blur detection in + most cases. + +- **Saturation metrics** + + - *PercentMaximal:* Percent of pixels at the maximum intensity value + of the image. + - *PercentMinimal:* Percent of pixels at the minimum intensity value + of the image. + +- **Intensity metrics** + + - *TotalIntensity:* Sum of all pixel intensity values. + - *MeanIntensity, MedianIntensity:* Mean and median of pixel + intensity values. + - *StdIntensity, MADIntensity:* Standard deviation and median + absolute deviation (MAD) of pixel intensity values. + - *MinIntensity, MaxIntensity:* Minimum and maximum of pixel + intensity values. + - *TotalArea/TotalVolume:* Number of pixels (or voxels) measured. + - *Scaling*: if *Yes* is chosen for "Include the image rescaling value?", + image’s rescaling value will be stored as a quality control metric. + This is useful in confirming that all images are rescaled by the same value, + given that some acquisition device vendors may output this value differently. + +- **Threshold metrics:** + + - *Threshold:* The automatically calculated threshold for each image + for the thresholding method of choice. + + The thresholds are recorded individually for + each image and also as aggregate statistics for all images in the + experiment. The mean, + median and standard deviation of the threshold values across all + images in the experiment are computed + for each of the threshold methods selected and recorded as a + measurement in the per-experiment table. + +References +^^^^^^^^^^ + +- Bray MA, Fraser AN, Hasaka TP, Carpenter AE (2012) “Workflow and + metrics for image quality control in large-scale high-content + screens.” *J Biomol Screen* 17(2):266-74. + `(link) `__ +- Field DJ (1997) "Relations between the statistics of natural images + and the response properties of cortical cells" *Journal of the + Optical Society of America.

Equals 1 + for a perfectly circular object. +- *Convex Area:* The area of a convex polygon containing the whole object. + Best imagined as a rubber band stretched around the object. +- *Solidity:* The proportion of the pixels in the convex hull that are + also in the object, i.e., *ObjectArea/ConvexHullArea*. +- *Extent:* The proportion of the pixels (2D) or voxels (3D) in the bounding box + that are also in the region. Computed as the area/volume of the object divided + by the area/volume of the bounding box. +- *EulerNumber:* The number of objects in the region minus the number + of holes in those objects, assuming 8-connectivity. +- *Center\_X, Center\_Y, Center\_Z:* The *x*-, *y*-, and (for 3D objects) *z-* + coordinates of the point farthest away from any object edge (the *centroid*). + Note that this is not the same as the *Location-X* and *-Y* measurements + produced by the **Identify** or **Watershed** + modules or the *Location-Z* measurement produced by the **Watershed** module. +- *BoundingBoxMinimum/Maximum\_X/Y/Z:* The minimum/maximum *x*-, *y*-, and (for 3D objects) + *z-* coordinates of the object. +- *BoundingBoxArea:* *(2D only)* The area of a box containing the object. +- *BoundingBoxVolume:* *(3D only)* The volume of a box containing the object. +- *Eccentricity:* *(2D only)* The eccentricity of the ellipse that has the same + second-moments as the region. The eccentricity is the ratio of the + distance between the foci of the ellipse and its major axis length. + The value is between 0 and 1. (0 and 1 are degenerate cases; an + ellipse whose eccentricity is 0 is actually a circle, while an + ellipse whose eccentricity is 1 is a line segment.) + + |MOSS_image0| + + +- *MajorAxisLength:* The length (in pixels) of the major axis of the + ellipse that has the same normalized second central moments as the + region. +- *MinorAxisLength:* The length (in pixels) of the minor axis of the + ellipse that has the same normalized second central moments as the + region. +- *EquivalentDiameter:* The diameter of a circle or sphere with the same area + as the object. +- *Orientation:* *(2D only)* The angle (in degrees ranging from -90 to 90 degrees) + between the x-axis and the major axis of the ellipse that has the + same second-moments as the region. +- *Compactness:* *(2D only)* Calculated as Perimeter\ :sup:`2`/4\*π\*Area, related to + Form Factor. A filled circle will have a compactness of 1, with irregular objects or + objects with holes having a value greater than 1. +- *MaximumRadius:* *(2D only)* The maximum distance of any pixel in the object to + the closest pixel outside of the object. For skinny objects, this is + 1/2 of the maximum width of the object. +- *MedianRadius:* *(2D only)* The median distance of any pixel in the object to the + closest pixel outside of the object. +- *MeanRadius:* *(2D only)* The mean distance of any pixel in the object to the + closest pixel outside of the object. +- *MinFeretDiameter, MaxFeretDiameter:* *(2D only)* The Feret diameter is the + distance between two parallel lines tangent on either side of the + object (imagine taking a caliper and measuring the object at various + angles). The minimum and maximum Feret diameters are the smallest and + largest possible diameters, rotating the calipers along all possible + angles. +- *Zernike shape features:* *(2D only)* These metrics of shape describe a binary object + (or more precisely, a patch with background and an object in the + center) in a basis of Zernike polynomials, using the coefficients as + features (*Boland et al., 1998*). Currently, Zernike polynomials from + order 0 to order 9 are calculated, giving in total 30 measurements. + While there is no limit to the order which can be calculated (and + indeed you could add more by adjusting the code), the higher order + polynomials carry less information. +- *Spatial Moment features:* *(2D only)* A series of weighted averages + representing the shape, size, rotation and location of the object. +- *Central Moment features:* *(2D only)* Similar to spatial moments, but + normalized to the object's centroid. These are therefore not influenced + by an object's location within an image. +- *Normalized Moment features:* *(2D only)* Similar to central moments, + but further normalized to be scale invariant. These moments are therefore + not impacted by an object's size (or location). +- *Hu Moment features:* *(2D only)* Hu's set of image moment features. These + are not altered by the object's location, size or rotation. This means that + they primarily describe the shape of the object. +- *Inertia Tensor features:* *(2D only)* A representation of rotational + inertia of the object relative to it's center. +- *Inertia Tensor Eigenvalues features:* *(2D only)* Values describing + the movement of the Inertia Tensor array. + + + +Technical notes +^^^^^^^^^^^^^^^ + +A number of the object measurements are generated by creating an ellipse +with the same second-moments as the original object region. This is +essentially the best-fitting ellipse for a given object with the same +statistical properties. Furthermore, they are not affected by the +translation or uniform scaling of a region. + +Following computer vision conventions, the origin of the X and Y axes is at the top +left of the image rather than the bottom left; the orientation of objects whose topmost point +is on their right (or are rotated counter-clockwise from the horizontal) will therefore +have a negative orientation, while objects whose topmost point is on their left +(or are rotated clockwise from the horizontal) will have a positive orientation. + +The Zernike features are computed within the minimum enclosing circle of +the object, i.e., the circle of the smallest diameter that contains all +of the object’s pixels. + +References +^^^^^^^^^^ + +- Rocha L, Velho L, Carvalho PCP, “Image moments-based structuring and + tracking of objects”, Proceedings from XV Brazilian Symposium on + Computer Graphics and Image Processing, 2002. `(pdf)`_ +- Principles of Digital Image Processing: Core Algorithms + (Undergraduate Topics in Computer Science): `Section 2.4.3 - + Statistical shape properties`_ +- Chrystal P (1885), “On the problem to construct the minimum circle + enclosing n given points in a plane”, *Proceedings of the Edinburgh + Mathematical Society*, vol 3, p. 30 +- Hu MK (1962), “Visual pattern recognition by moment invariants”, *IRE + transactions on information theory*, 8(2), pp.179-187 `(link)`_ + +.. _(pdf): http://sibgrapi.sid.inpe.br/col/sid.inpe.br/banon/2002/10.23.11.34/doc/35.pdf +.. _Section 2.4.3 - Statistical shape properties: http://www.scribd.com/doc/58004056/Principles-of-Digital-Image-Processing#page=49 +.. _(link): https://ieeexplore.ieee.org/abstract/document/1057692 +.. |MOSS_image0| image:: {ECCENTRICITY_ICON} +""".format( + **{ + "ECCENTRICITY_ICON": cellprofiler.gui.help.content.image_resource( + "MeasureObjectSizeShape_Eccentricity.png" + ) + } +) + + +class MeasureObjectSizeShape(Module): + module_name = "MeasureObjectSizeShape" + variable_revision_number = 3 + category = "Measurement" + + def create_settings(self): + """Create the settings for the module at startup and set the module name + + The module allows for an unlimited number of measured objects, each + of which has an entry in self.object_groups. + """ + self.objects_list = LabelListSubscriber( + "Select object sets to measure", + [], + doc="""Select the object sets whose size and shape you want to measure.""", + ) + self.spacer = Divider(line=True) + + self.calculate_advanced = Binary( + text="Calculate the advanced features?", + value=False, + doc="""\ +Select *{YES}* to calculate additional statistics for object moments +and intertia tensors in **2D mode**.

For example, if you choose a + scale of 2, each pixel in the image (excluding some border pixels) + will be compared against the one that is two pixels to the right. + + Thirteen measurements are then calculated for the image by performing + mathematical operations on the co-occurrence matrix (the formulas can + be found `here`_): + + - *AngularSecondMoment:* Measure of image homogeneity. A higher + value of this feature indicates that the intensity varies less in + an image. Has a value of 1 for a uniform image. + - *Contrast:* Measure of local variation in an image, with 0 for a + uniform image and a high value indicating a high degree of local + variation. + - *Correlation:* Measure of linear dependency of intensity values in + an image. For an image with large areas of similar intensities, + correlation is much higher than for an image with noisier, + uncorrelated intensities. Has a value of 1 or -1 for a perfectly + positively or negatively correlated image, respectively. + - *Variance:* Measure of the variation of image intensity values. + For an image with uniform intensity, the texture variance would be + zero. + - *InverseDifferenceMoment:* Another feature to represent image + contrast. Has a low value for inhomogeneous images, and a + relatively higher value for homogeneous images. + - *SumAverage:* The average of the normalized grayscale image in the + spatial domain. + - *SumVariance:* The variance of the normalized grayscale image in + the spatial domain. + - *SumEntropy:* A measure of randomness within an image. + - *Entropy:* An indication of the complexity within an image. A + complex image produces a high entropy value. + - *DifferenceVariance:* The image variation in a normalized + co-occurrence matrix. + - *DifferenceEntropy:* Another indication of the amount of + randomness in an image. + - *InfoMeas1:* A measure of the total amount of information contained + within a region of pixels derived from the recurring spatial + relationship between specific intensity values. + - *InfoMeas2:* An additional measure of the total amount of information + contained within a region of pixels derived from the recurring spatial + relationship between specific intensity values. It is a complementary + value to InfoMeas1 and is on a different scale. + +**Note**: each of the above measurements are computed for different +'directions' in the image, specified by a series of correspondence vectors. +These are indicated in the results table in the *scale* column as n_00, n_01, +n_02... for each scale *n*. In 2D, the directions and correspondence vectors *(y, x)* +for each measurement are given below: + +- _00 = horizontal -, 0 degrees (0, 1) +- _01 = diagonal \\\\, 135 degrees or NW-SE (1, 1) +- _02 = vertical \|, 90 degrees (1, 0) +- _03 = diagonal /, 45 degrees or NE-SW (1, -1) + +When analyzing 3D images, there are 13 correspondence vectors *(y, x, z)*: + +- (1, 0, 0) +- (1, 1, 0) +- (0, 1, 0) +- (1,-1, 0) +- (0, 0, 1) +- (1, 0, 1) +- (0, 1, 1) +- (1, 1, 1) +- (1,-1, 1) +- (1, 0,-1) +- (0, 1,-1) +- (1, 1,-1) +- (1,-1,-1) + +In this case, an image makes understanding their directions easier. +Imagine the origin (0, 0, 0) is at the upper left corner of the first image +in your z-stack. Yellow vectors fall along the axes, and pairs of vectors with +matching colors are reflections of each other across the x axis. The two +images represent two views of the same vectors. Images made in `GeoGebra`_. + +|MT_image0| |MT_image1| + +Technical notes +^^^^^^^^^^^^^^^ + +To calculate the Haralick features, **MeasureTexture** normalizes the +co-occurrence matrix at the per-object level by basing the intensity +levels of the matrix on the maximum and minimum intensity observed +within each object. This is beneficial for images in which the maximum +intensities of the objects vary substantially because each object will +have the full complement of levels. + +References +^^^^^^^^^^ + +- Haralick RM, Shanmugam K, Dinstein I.

The effect is to return parts of the image that have a linear + intensity distribution and suppress dots of the same size. + - Binary, grayscale + * - *Remove* + - Removes pixels that are otherwise surrounded by others (4 connected).

This means that blobs are reduced to single points + and blobs with holes are reduced to rings if shrunken indefinitely. + - Binary + * - *SkelPE* + - Performs a skeletonizing operation using the metric, PE * D to control the + erosion order. PE is the Poisson Equation (see Gorelick, "Shape representation + and classification using the Poisson Equation", IEEE Transactions on Pattern + Analysis and Machine Intelligence V28, # 12, 2006) evaluated within the + foreground with the boundary condition that the background is zero. D is the + distance transform (distance of a pixel to the nearest edge).

The resulting images can then +be uniformly analyzed to find features that correlate with position in +an ideal representation of the worm, such as the head or gut. +**StraightenWorms** works by calculating a transform on the image that +translates points in the image to points on the ideal worm. +**UntangleWorms** idealizes a worm as a series of control points that +define the worm’s shape and length. The training set contains +measurements of the width of an ideal worm at each control point. +Together, these can be used to reconstruct the worm’s shape and +correlate between the worm’s location and points on the body of an ideal +worm. **StraightenWorms** produces objects representing the straight +worms and images representing the intensity values of a source image +mapped onto the straight worms. The objects and images can then be used +to compute measurements using any of the object measurement modules, for +instance, **MeasureTexture**. The module can be configured to make +intensity measurements on parts of the worm, dividing the worm up into +pieces of equal width and/or height. Measurements are made longitudinally +in stripes from head to tail and transversely in segments across the +width of the worm. Longitudinal stripes are numbered from left to right +and transverse segments are numbered from top to bottom. The module will +divide the worm into a checkerboard of sections if configured to measure +more than one longitudinal stripe and transverse segment. These are +numbered by longitudinal stripe number, then transverse segment number. +For instance, “Worm\_MeanIntensity\_GFP\_L2of3\_T1of4”, is a measurement +of the mean GFP intensity of the center stripe (second of 3 stripes) of +the topmost band (first of four bands). Measurements of longitudinal +stripes are designated as “T1of1” indicating that the whole worm is one +transverse segment. Likewise measurements of transverse segments are +designated as “L1of1” indicating that there is only one longitudinal +stripe. Both mean intensity and standard deviation of intensity are +measured per worm sub-area. While **StraightenWorms** can straighten a +color image, the module needs a grayscale image to make its intensity +measurements. For a color image, the red, green and blue channels are +averaged to yield a grayscale image. The intensity measurements are then +made on that grayscale image. + +| + +============ ============ =============== +Supports 2D? Supports 3D?

Objects that match are assigned the same number, or +label, throughout the entire movie. There are several options for the +method used to find a match. Choose among these options based on which +is most consistent from frame to frame of your movie. + +- *Overlap:* Compares the amount of spatial overlap between identified + objects in the previous frame with those in the current frame.

The closest + objects to each other will be assigned the same number (label). + Distances are measured from the perimeter of each object. + + |image1| Recommended for cases where the objects are not very + crowded but where *Overlap* does not work sufficiently well, which is + the case for movies with low frame rates relative to object motion. + +- *Measurements:* Compares each object in the current frame with + objects in the previous frame based on a particular feature you have + measured for the objects (for example, a particular intensity or + shape measurement that can distinguish nearby objects). The object + with the closest-matching measurement will be selected as a match and + will be assigned the same number (label). This selection requires + that you run the specified **Measure** module previous to this module + in the pipeline so that the measurement values can be used to track + the objects. +- *Follow Neighbors:* Uses the multiobject tracking approach described + by *Delgado-Gonzalo et al., 2010*. This approach assumes objects move + in a coordinated way (contrary to LAP). An object's movement + direction is more likely to be in agreement with the movement + directions of its "neighbors". The problem is formulated as an + optimization problem and solved using LAP algorithm (same as in LAP + method). + + |image2| Recommended for cases where the objects are moving in + synchronized way. In this case it may work better than *LAP*. This + approach works well for yeast colonies grown on agar. + +- *LAP:* Uses the linear assignment problem (LAP) framework. The linear + assignment problem (LAP) algorithm (*Jaqaman et al., 2008*) addresses + the challenges of high object density, motion heterogeneity, + temporary disappearances, and object merging and splitting. The + algorithm first links objects between consecutive frames and then + links the resulting partial trajectories into complete trajectories. + Both steps are formulated as global combinatorial optimization + problems whose solution identifies the overall most likely set of + object trajectories throughout a movie. + + Tracks are constructed from an image sequence by detecting objects in + each frame and linking objects between consecutive frames as a first + step. This step alone may result in incompletely tracked objects due + to the appearance and disappearance of objects, either in reality or + apparently because of noise and imaging limitations. To correct this, + you may apply an optional second step which closes temporal gaps + between tracked objects and captures merging and splitting events. + This step takes place at the end of the analysis run. + + |image3| Some recommendations on optimizing the LAP settings + + - *Work with a minimal subset of your data:* Attempting to optimize + these settings by examining a dataset containing many objects may + be complicated and frustrating. Therefore, it is a good idea to + work with a smaller portion of the data containing the behavior of + interest. + + - For example, if splits characterize your data, trying narrowing + down to following just one cell that undergoes a split and + examine a few frames before and after the event. + - You can insert the **Crop** module to zoom in a region of + interest, optimize the settings and then either remove or + disable the module when done. + - You can also use the **Input** modules to limit yourself to a + few frames under consideration. For example, use the filtering + settings in the **Images** module to use only certain files + from the movie in the pipeline. + + - *Begin by optimizing the settings for the first phase of the LAP:* + The 2nd phase of the LAP method depends on the results of the + first phase. Therefore, it is a good idea to optimize the first + phase settings as the initial step. + + - You can disable 2nd phase calculation by selecting *No* for + "Run the second phase of the LAP algorithm?" + - By maximizing the number of correct frame-to-frame links in the + first phase, the 2nd phase will have less candidates to + consider for linking and have a better chance of closing gaps + correctly. + - If tracks are not being linked in the first phase, you may need + to adjust the number of standard deviations for the search + radius and/or the radius limits (most likely the maximum + limit). See the help for these settings for details. + + - *Use any visualization tools at your disposal:* Visualizing the + data often allows for easier decision making as opposed to sorting + through tabular data alone. + + - The `R `__ open-source software + package has analysis and visualization tools that can query a + database. + - `CellProfiler Tracer `__ is a + version of CellProfiler Analyst that contains tools for + visualizing time-lapse data that has been exported using the + **ExportToDatabase** module. + + This Nearest Neighborhood method of this module was prepared by Filip + Mroz, Adam Kaczmarek and Szymon Stoma.

If the result of +the untangling is not satisfactory (e.g., it is unable to detect long +worms or is too stringent about shape variation) and you do not wish to +re-train, you can adjust the provided worm model manually by opening the +.xml file in a text editor and changing the values for the fields +defining worm length, area etc. You may also want to adjust the “Maximum +Complexity” module setting which controls how complex clusters the +untangling will handle. Large clusters (> 6 worms) may be slow to +process. + +References +^^^^^^^^^^ + +- Wählby C, Kamentsky L, Liu ZH, Riklin-Raviv T, Conery AL, O’Rourke + EJ, Sokolnicki KL, Visvikis O, Ljosa V, Irazoqui JE, Golland P, + Ruvkun G, Ausubel FM, Carpenter AE (2012).

This works by +'flooding' pixel intensity valleys (that is, areas of low intensity) from seed +objects. When the water from one flooded valley meets the water from a nearby +but different flooded valley, this is the "watershed line" and defines the +separation between two objects. + + +The Watershed module helps users to define what their valley and seed images +will be. The valley image is determined by the *declump* method. For shape-based +declumping, the inverted distance transform of the binary (black and white) +input image will be used. If intensity based declumping is used, the inverted +intensity will be used, meaning that areas of high pixel intensity will be set +as the bottom of valleys. + + +Seed objects can be calculated from the distance transform of your input binary +image by selecting the *Distance* method. This method will calculate seed +objects for pixels that are distant from the background (black pixels), which +are typically the centers of nuclei.

Abstraction #1)** + - Define what it means to "run a benchmark" + - Input: Dataset specification, Tool specification, Metric specification + - Output: Structured results (timing, memory, correctness) + - Contract is tool-agnostic — works for OpenHCS, CellProfiler, ImageJ, custom scripts + +2. **Dataset Registry (Orthogonal Abstraction #2)** + - Declarative dataset specifications + - Each dataset is a frozen dataclass: `BBBCDataset(id, url, expected_files, ground_truth)` + - Auto-download, auto-verify, auto-cache + - No imperative "download this, unzip that" — declare what you need, system handles it + +3. **Tool Adapter Protocol (Orthogonal Abstraction #3)** + - Each tool (OpenHCS, CellProfiler, ImageJ) implements same interface + - `ToolAdapter.run(dataset, pipeline_config) -> BenchmarkResult` + - Adapters handle tool-specific invocation, but return normalized results + - Adding new tool = implement adapter, not modify benchmark code + +4. **Metric Collectors (Orthogonal Abstraction #4)** + - Time, memory, GPU utilization, correctness — each is independent collector + - Collectors attach to tool execution via context managers + - Declarative: `@collect_metrics(time=True, memory=True, gpu=True)` + - No manual instrumentation scattered through code + +5. **Result Storage (Orthogonal Abstraction #5)** + - Structured storage: `results/{tool}/{dataset}/{metric}/{timestamp}.json` + - Immutable results (append-only, never modify) + - Automatic versioning (git-style: results are commits) + - Query interface: "Give me all timing results for BBBC021 across all tools" + +6. **Comparison Engine (Orthogonal Abstraction #6)** + - Takes N tool results, produces comparison tables/plots + - Declarative comparison specs: "Compare OpenHCS vs CellProfiler on processing_time" + - Generates Nature Methods-ready figures automatically + - No manual matplotlib wrangling — declare what you want, system renders it + +###

Current Branch Status + +### 3.1 What Is Already Done + +The branch has already established most of the typed runtime/compiler foundation needed for richer semantics: + +1. `CompiledStepPlan` is the compiler/runtime execution SSOT. +2. Function patterns are normalized and compiled before runtime. +3. `CallableContract` centralizes callable metadata extraction. +4. Artifact graph extraction and per-invocation ownership are typed. +5. `RuntimeValue`, `RuntimeValueSchema`, and `RuntimeValueStore` exist. +6. `ArtifactKind` is preserved through compile and runtime validation. +7. Generated CellProfiler wrappers execute through the OpenHCS orchestrator/runtime path. +8. Produced images, object labels, measurements, and relationships now have real runtime representation. +9. The CellProfiler symbol table already distinguishes: + - runtime artifact inputs + - external image inputs +10. Minimal `.cppipe -> generate -> import -> orchestrator execute` works. +11. `.cppipe` parsing now preserves ordered typed setting records instead of only last-write dict values. +12. Converter setup modules now compile into a typed image/setup schema that lowers `NamesAndTypes` aliases into selector-bearing `source_bindings`. +13. Compiler/runtime plans now carry explicit stable step identity plus a typed main-input dependency record instead of relying purely on implicit `step_index - 1` assumptions. + - The current field name is `step_scope_id`, but semantically this is just a compiled stable identity string copied forward from the existing step token/scope machinery. + - Runtime execution does **not** use `ObjectState`; a later cleanup may rename this to `step_identity` or `step_node_id`. +14. Artifact input/output plans now also carry scope-based producer/source identity alongside legacy step indexes. +15. Selector-bearing runtime source resolution is now wired for the native cases OpenHCS can currently express: + - `STEP_INPUT` bindings resolve against the current pattern-group file universe and select typed views from the current stack. + - `PIPELINE_START` bindings resolve against the original axis file universe with inherited current-scope component constraints. +16. Metadata extraction rules are now first-class core source-binding state rather than converter-local strings: + - compiled `StepSourceBindingsConfig` / `CompiledSourceBindingPlan` preserve typed regex-backed metadata rules + - generated pipelines emit those rules directly + - runtime candidate parsing augments native parser metadata from those rules instead of guessing +17. Metadata-only selectors can now resolve when the binding plan provides enough compiled metadata extraction semantics. +18. Current-scope inheritance is now opportunistic rather than rigid: + - inherited scope fields only constrain candidates that actually expose those fields + - this keeps pipeline-start matches usable for cases like illumination files that share folder identity but not full well/site/channel metadata +19. Metadata-based `NamesAndTypes` image-set matching now compiles into a typed cross-alias match plan: + - the parser preserves repeated setup settings needed for match dimensions + - escaped legacy `.cppipe` match payloads are decoded before literal parsing + - generated `source_bindings` now carry the match plan all the way into runtime resolution +20. The `GrayToColor` absorbed-library gap is resolved through one module-level typed dispatcher instead of mode-specific registry hacks: + - repeated stack/composite settings are preserved through a dedicated module-settings binding layer + - `GrayToColor` source image discovery is now shared SSOT in converter code instead of ad hoc local parsing + - BBBC021 now converts successfully with 20 processing modules and no failed absorbed modules +21. The setup/image schema is now exposed beyond the immediate converter internals: + - generated `.cppipe` pipeline objects and prepared runtime pipelines carry the compiled pipeline-level `source_schema` + - dataset specs can declare canonical reference `.cppipe` URLs + - the OpenHCS benchmark adapter can resolve converted pipeline runs from either a local `.cppipe` path or a dataset-owned canonical `.cppipe` reference +22. Pipeline-level image schema ownership now lives in core OpenHCS concepts instead of converter-local dataclasses: + - [openhcs/core/pipeline_image_schema.py](/home/ts/code/projects/openhcs-benchmark-platform/openhcs/core/pipeline_image_schema.py:1) now owns `CellProfilerImageSchema`, `ImageAssignment`, `GroupingPlan`, `ImagesRule`, and legacy alias strategies + - [benchmark/converter/source_schema.py](/home/ts/code/projects/openhcs-benchmark-platform/benchmark/converter/source_schema.py:1) now acts as a lowering module that compiles setup modules into those core schema types + - generated/prepared pipeline objects, symbol-table compilation, and benchmark/runtime wiring now import the schema from core directly +23. The absorbed CellProfiler import/materialization surface is now cleaner and exercised on real paths: + - `csv_materializer(...)` is a first-class exported materialization preset used by absorbed measurement/export modules + - `openhcs.core.memory.decorators` is a real core import surface rather than an implicit missing module + - active and ExampleFly-relevant absorbed functions now import cleanly under unit coverage + - the benchmark adapter now executes the real shipped `ExampleFly.cppipe` end to end and materializes non-empty CSV outputs +24. The in-tree `.cppipe` corpus is now tracked explicitly instead of implicitly: + - shipped fixtures are classified as either supported or structurally invalid + - adapter-level preparation failures are wrapped as `ToolExecutionError` with the original compatibility diagnostic preserved + - `ExampleHuman.cppipe` is now asserted as a known invalid reduced fixture rather than silently encouraging weaker symbol validation +25. The accepted corpus now includes canonical BBBC021 reference pipeline snapshots in-tree: + - `BBBC021_analysis.cppipe` and `BBBC021_illum.cppipe` now prepare successfully as supported corpus members + - real setup-module lowering for those files is asserted under unit coverage + - the typed image schema for those files now has explicit acceptance checks for grouping, metadata match dimensions, and selector-bearing assignments +26. PURE_2D absorbed-function execution now preserves tuple-shaped side outputs generically: + - the shared registry slice executor now aggregates `(main_output, side_output...)` returns instead of assuming every per-slice result is a bare 2D array + - 2D auxiliary image/label outputs restack correctly + - tabular auxiliary outputs aggregate across slices instead of collapsing or failing + - per-slice outputs with `slice_index` fields now get the real runtime slice index injected during aggregation +27. Real acceptance coverage now extends beyond the earlier in-tree subset: + - canonical `BBBC021_illum.cppipe` executes through the real orchestrator/runtime path on synthetic BBBC021-shaped data + - `ExampleFly.cppipe` CSV assertions now validate semantic headers, not just file existence + - generated `RelateObjects` acceptance now validates concrete relationship/measurement CSV schemas +28. `NamesAndTypes` order-based image-set matching is now part of the supported semantics: + - the setup-module compiler now lowers `Image set matching method:Order` into a typed `SourceBindingMatchPlan(method=ORDER)` + - the runtime adapter resolves order-based pipeline-start pairings generically by matching the current step-input image-set index against the ordered target alias candidate list + - support is implemented in the nominal core match-plan resolver path rather than as converter- or module-local glue +29. Common CellProfiler processing-module artifact contracts can now be inferred through a nominal typed pattern family instead of silently defaulting to empty contracts: + - infrastructure modules now have an explicit no-artifact contract builder + - common single image/object input-output shapes infer `ArtifactSpec` inputs/outputs from declared CellProfiler settings + - unmodeled processing modules now fail loudly with a compatibility diagnostic instead of pretending they have no runtime semantics + - canonical BBBC021 illumination modules now compile real `CorrectIlluminationCalculate` image inputs/outputs +30. Converter setting/function resolution cleanup removed two advisor-detected duplication points: + - CellProfiler setting-name normalization now has one shared authority used by the binder, pipeline generator, and parameter-mapping tooling + - `SettingsBinder` exposes typed public parsing and frozen provenance rows instead of private-method coupling + - MeasureTexture/MeasureColocalization raw-function variant selection now shares one nominal scoped-measurement resolver base +31. Generated/prepared `.cppipe` runtime records now share one nominal base for common generated-pipeline context: + - `cppipe_path`, processing/infrastructure modules, `source_schema`, and generated code state are no longer duplicated across sibling dataclasses +32. Real `NamesAndTypes` assignment layouts now compile through a nominal strategy family instead of an incidental string split: + - repeated full assignment blocks, repeated rule-row assignments, and single-assignment layouts each have explicit registered strategies + - canonical BBBC021 analysis now exposes the real alias set (`DAPI`, `Actin`, `Tubulin`, and illumination-function aliases) instead of collapsing to the stale `DNA` preamble alias + - `benchmark/converter/source_schema.py` reports clean under the nominal refactor advisor after this pass +33. Canonical BBBC021 analysis now executes end to end through generated OpenHCS runtime plumbing on synthetic BBBC021-shaped data: + - legacy escaped `.cppipe` metadata/filter literals decode before setup-schema lowering + - `PIPELINE_START` metadata source resolution uses the setup-declared physical source universe when the virtual workspace cannot expose non-native illumination files + - absorbed CellProfiler contracts are applied after named image/artifact resolution so module adapters can compose semantic inputs before raw PURE_2D slicing + - aligned 3D runtime kwargs, singleton label stacks, and multi-image CellProfiler inputs are normalized through typed runtime execution rules instead of runtime fallbacks + - `MeasureTexture` and `MeasureGranularity` object variants now resolve through nominal function-resolution strategies and the shared object-measurement input policy + - the real path now reaches successful orchestrator execution across illumination correction, primary/secondary/tertiary objects, object-to-image conversion, RGB composition, overlays, intensity/size/texture/granularity/neighborhood measurements, and CSV materialization +34. Pipeline-start source resolution now covers non-native CellProfiler sidecar source files without weakening virtual-workspace validation: + - virtual workspaces still require real `workspace_mapping` metadata before pipeline-start source resolution can run + - once that invariant is satisfied, the source universe also includes physical plate-root files so selector-bearing bindings can resolve `.mat` illumination matrices and similar sidecar source payloads + - generated pipeline-start source-bound steps now emit `GroupBy.NONE` explicitly when executing over site/channel source universes, avoiding runtime auto-resolution noise + - a new fast integration fixture compiles and executes a real `LoadImages + CorrectIlluminationApply` `.cppipe` that resolves both the raw image and a MATLAB illumination matrix through `SourceBindingOrigin.PIPELINE_START` +35. The CellProfiler symbol table now models workspace identity as `(name, kind)` instead of plain string name: + - image/object name overlap is allowed when the image binding is declared by setup schema, matching real CellProfiler pipelines such as current official `ExampleHuman.cppipe` + - unknown object references still fail loudly + - an image reference that collides with an existing object name still fails unless the source schema explicitly declares that image binding + - `RelateObjects` now accepts both current `Select the parent/child objects` settings and older `Parent objects` / `Child objects` schema aliases through the shared setting-name family path +36. The in-tree `ExampleHuman.cppipe` fixture now tracks the current official CellProfiler example instead of the stale reduced invalid fixture: + - the corpus classifies `ExampleHuman` as supported rather than known-invalid + - corpus preparation coverage now exercises the real `Images`, `Metadata`, `NamesAndTypes`, `Groups`, dual `IdentifyPrimaryObjects`, `RelateObjects`, `IdentifySecondaryObjects`, `IdentifyTertiaryObjects`, measurements, `OverlayOutlines`, `SaveImages`, and `ExportToSpreadsheet` structure + - the previously intentional `Cytoplasm` producer gap is gone because the real pipeline contains the missing tertiary-object producer +37. Current official `ExampleHuman.cppipe` now executes through the real generated OpenHCS runtime path when its setup schema is materialized into an OpenHCS virtual workspace: + - `Images` / `Metadata` / `NamesAndTypes` / `Groups` compile into source schema and source bindings instead of being treated as unabsorbed runtime modules + - the materialized workspace preserves the three named source images (`DNA`, `PH3`, `cellbody`) as OpenHCS-addressable views + - object-only CellProfiler modules such as `IdentifyTertiaryObjects` no longer iterate over a fake 3-plane image stack when their true semantic inputs are object labels + - per-object measurement modules now resolve each declared image input independently and measure each declared image/object pair instead of using one composed source image + - coupled image-pair measurements such as `MeasureColocalization` keep the composed multi-image payload as one semantic input while still running through the same object-measurement path + - acceptance asserts that `Cytoplasm` remains a single 2D object-label artifact and that intensity measurements are materialized +38. CellProfiler image execution mode dispatch is now nominal and advisor-clean: + - `CellProfilerImageExecutionStrategy` is an auto-registered ABC family keyed by `CellProfilerImageExecutionMode` + - natural, full-stack, and aligned multi-image-stack execution modes are separate typed strategies + - `benchmark/cellprofiler_compat/module_execution.py` reports zero findings under the nominal refactor advisor after this pass + +### 3.2 What Is Still Missing + +The biggest unresolved items are now: + +1. Setup-module semantics are now exposed as a core-owned pipeline-level image schema during generated-pipeline preparation and benchmark execution, but they are not yet a broader editable GUI/ObjectState pipeline concept. +2. `NamesAndTypes` image-set matching semantics are now modeled for both metadata-based and order-based paths, but broader real-pipeline coverage and any remaining match variants still need work. + - `Metadata` matching lowers into a typed cross-alias plan + - `Order` matching now resolves through a generic runtime image-set index strategy + - unsupported variants should continue to fail loudly until modeled natively +3. GUI/ObjectState/pycodify do not yet own richer source-binding state as an editable first-class step concept. +4. The main-input edge is now explicit in compiled plans, but the external execution model is still list-based rather than first-class graph-based. +5. The compiled identity record is semantically useful, but its current `step_scope_id` naming still reflects pre-compilation/UI vocabulary more than ideal runtime/compiler terminology. +6. Real BBBC pipelines are only partially accepted end to end. + - live BBBC021 setup/image schema compilation now succeeds + - live BBBC021 conversion now succeeds end to end at code-generation time + - a BBBC021-style generated pipeline now executes through the OpenHCS orchestrator with typed named-channel bindings + - canonical BBBC021 illumination now carries explicit inferred image artifact contracts for illumination functions instead of empty contracts + - canonical in-tree BBBC021 reference snapshots now prepare successfully and preserve typed schema facts under direct test coverage + - canonical `BBBC021_analysis.cppipe` now executes through the orchestrator on synthetic BBBC021-shaped data and validates the core generated runtime path + - canonical `BBBC021_illum.cppipe` now executes successfully as a real converted pipeline shape + - LoadImages-style `.mat` illumination sidecar binding now executes through the real generated pipeline/orchestrator path + - symbol-table semantics now support real pipelines that reuse the same lexical alias for an image and an object in different CellProfiler workspaces + - canonical dataset-owned `.cppipe` references can now be resolved through the benchmark adapter instead of only local ad hoc files + - ExampleFly now executes end to end as a real shipped `.cppipe` shape and materializes measurement CSV outputs on disk + - current official ExampleHuman now executes end to end through the generated orchestrator path on synthetic official-shaped data + - a generated `RelateObjects` pipeline now executes through the orchestrator and materializes both relationship and measurement CSV outputs + - the next gap is broadening accepted real-pipeline coverage beyond BBBC021 / ExampleFly / ExampleHuman and validating against more real downloaded dataset layouts +7. Export and relationship-heavy semantics now have initial real-output validation with concrete CSV schema assertions, but not broad corpus-level validation across many real converted pipelines. +8. Benchmarking is no longer ahead of the remaining CellProfiler semantics, but it should still stay secondary to broader semantic validation. +9. The broader absorbed-function corpus still needs continued cleanup beyond the currently exercised import/materialization surface. + +--- + +## 4. Problem Statement + +OpenHCS currently has two meaningful data planes: + +1. **Primary image plane** + - the `main_data_arg` + - the ordinary step input/output stack flow + +2. **Runtime artifact plane** + - images produced by prior modules + - object labels + - measurement tables + - relationships + - persisted through the typed runtime store + VFS boundary + +CellProfiler requires a third plane: + +3. **Named semantic source plane** + - semantic image names such as `OrigBlue`, `DNA`, `GFP`, `Actin` + - usually views/selectors over the step input container + - sometimes resolved from microscope metadata/component coordinates when the data is not already present in the step input container + - distinct from runtime-produced artifacts even if both end up as the same typed image value once resolved + +Today, that third plane is only partially represented: + +1. the symbol table knows such names exist +2. conversion now preserves repeated setup settings and lowers setup modules into typed alias selectors +3. generated-pipeline preparation now carries a pipeline-level image schema and the benchmark adapter can target canonical dataset-owned `.cppipe` references +4. the GUI/codegen layer does not yet expose the richer selector-bearing source state as a mature editable concept +5. broader corpus-level validation still needs to prove that the compiled source plane is correct on real dataset layouts beyond the currently accepted pipelines + +That is the core semantic gap. + +--- + +## 5. Architectural Constraints + +These constraints are mandatory for the remaining work. + +### 5.1 No Fake Wrapper Layer + +Do not solve this by building local wrapper classes around dicts. + +A new type is only justified if it owns one or more of: + +1. identity +2. validation invariant +3. serialization contract +4. compiler snapshot boundary +5. runtime resolution rule +6. GUI-editable state + +### 5.2 No Silent Fallback + +No direct-VFS fallback and no “best effort” image substitution. + +If a compiled source binding cannot be resolved, runtime must fail loudly with: + +1. binding name +2. step/module identity +3. expected source selector +4. axis/group scope + +### 5.3 No Runtime O(n) Module-Specific Solving + +Do not accumulate many `if module_name == ...` branches in the executor. + +Module-specific knowledge should be compiled into declarative semantics once, then executed generically. + +### 5.4 Do Not Overload the Function Pattern + +The dict-of-lists function pattern already means: + +1. behavior selection by component/group + +It should **not** become the data-source model. + +Function pattern answers: + +1. what code runs for this group? + +Source binding plan answers: + +1. what named inputs exist for this group? + +Those are related but distinct layers. + +### 5.5 The GUI and Code Round-Trip Matter + +Any new user-visible concept must fit: + +1. `ObjectState` +2. `pyqt-reactive` forms +3. `pycodify` export/import +4. preview formatting in the pipeline editor + +### 5.6 Respect Microscope/Metadata Ownership + +The source of truth for real input coordinates is: + +1. microscope handler +2. metadata handler +3. metadata cache +4. orchestrator component keys + +CellProfiler source bindings must compile into those existing semantics, not parallel them. + +### 5.7 Respect the Existing Step Input Model + +OpenHCS steps already operate on a primary `main_data_arg`, which may be a multi-image or multi-dimensional container. + +Source bindings must not assume that “many semantic names” means “many separately loaded arrays”. + +Prefer this order of interpretation: + +1. semantic name maps to a typed selector/view over the existing step input container +2. if the named data is not already present in that container, resolve it through the microscope/metadata path + +So source bindings are primarily a **name-to-view / name-to-selector** layer, not a forced side-channel image loader. + +### 5.8 Preserve OpenHCS Genericity + +OpenHCS should not gain a “CellProfiler workspace” core abstraction. + +It should gain a more generic notion of: + +1. named external source bindings +2. typed artifact semantics +3. compiled input/output contracts + +CellProfiler then becomes one client of those abstractions. + +--- + +## 6. Target Architecture + +### 6.1 Layering + +The intended source-of-truth chain should be: + +```text +Editable step/source binding config (ObjectState-visible) + -> compiler snapshot + -> compiled source binding plan + -> runtime source resolver + -> typed image/object/measurement values + -> materialization / export +``` + +This must sit beside, not inside, the existing artifact chain: + +```text +callable contract + -> artifact graph + -> compiled artifact input/output plans + -> runtime artifact store +``` + +### 6.2 Core Concepts to Introduce + +The remaining missing domain types are around source binding, not around artifact output. + +Preferred domain split: + +1. **Editable/source-layer step field** + - a dataclass family owned by OpenHCS core + - exposed as a real `FunctionStep` constructor field + - serializable + - ObjectState-friendly + - pycodify-friendly + +2. **Compiled/source-layer plan** + - immutable + - compiler-owned + - no hidden dicts + - no signature probing at runtime + +3. **Runtime/source-layer resolution** + - uses microscope metadata, component keys, and filemanager + - returns explicit named image payloads + +Candidate conceptual types: + +1. `SourceBindingKind` +2. `SourceSelector` +3. `ExternalImageBinding` +4. `GroupedExternalImageBindings` +5. `StepSourceBindingsConfig` +6. `CompiledSourceBindingPlan` + +These names are illustrative; exact names can change. + +### 6.3 Relationship to Existing OpenHCS Concepts + +### `InputSource` + +`InputSource.PIPELINE_START` is a coarse step-wide source selector. + +It should remain valid, but it is not enough for CellProfiler. + +Correct relationship: + +1. `InputSource` says which broad domain a step reads from. +2. source bindings refine which **named images** inside that domain are needed. + +### `FunctionPattern` + +`CompiledFunctionPattern` remains the SSOT for grouped behavior. + +Source bindings should reuse the same group-key vocabulary where appropriate, but must remain a distinct plan. + +### `FunctionStep` + +`FunctionStep` is constructor-introspected by the UI/state system rather than declared as a dataclass. + +That means source bindings should be introduced as a real first-class step field, not a hidden post-hoc attribute and not nested under `processing_config`. + +Correct relationship: + +1. `func` declares behavior +2. `source_bindings` declares semantic named input views/selectors +3. `processing_config` continues to own operational knobs like `group_by`, `variable_components`, and `input_source` + +### `RuntimeValueStore` + +Produced images continue to live in the runtime artifact plane. + +External images are **not** runtime-produced artifacts. They are resolved source inputs. + +However, both should converge to the same **typed image value semantics** once resolved. + +That means: + +1. external image binding resolution returns typed image values +2. runtime-produced images are read as typed image values +3. the executor should then be able to treat them symmetrically + +### `Metadata and UI Component Selection` + +The GUI already exposes metadata-backed component selection through the generic component-selection provider path. + +Correct relationship: + +1. metadata and microscope handlers define what coordinates/components exist +2. source bindings store typed selectors in that vocabulary +3. the UI renders human labels through the existing metadata display path + +So source bindings should store stable component/metadata selectors, while the GUI displays names like `Channel 1 | DAPI` using the existing provider stack. + +--- + +## 7. Infrastructure Module Mapping + +The CellProfiler infrastructure modules should no longer be treated as vague skipped prelude. + +### `Images` + +Maps to: + +1. image-discovery assumptions +2. input-domain description + +Likely compile role: + +1. validates that image-loading mode is representable in OpenHCS +2. contributes to source binding normalization + +### `Metadata` + +Maps to: + +1. filename/metadata component interpretation +2. source selectors based on well/site/channel/z/timepoint or other metadata + +Likely compile role: + +1. contributes selector rules +2. validates available metadata fields against the microscope handler + +### `NamesAndTypes` + +This is the most important infrastructure module. + +It maps: + +1.
