!Manipulating objects in QuPath

Scripts mostly taken from Pete, and also from the forums. For easy access and reference.

TOC

Alignment: Several scripts to assist in alignment as of M9. Store scripts make files using the Affine transformation while
TransferObjects uses the stored file in the Affine folder with the current image name to move objects into it.
The final result is that one set of files can be generated for the transforms, and those transforms can be accessed to move objects
back and forth between the images.

Change annotations into Cell objects.groovy - Converts annotations into PathCellObjects, which allows certian functions to work within
them, namely Subcellular detection.

Change some annotations into detections.groovy - Similar to above, except with generic detections.
Change some annotations into detections 0.2.0M11.groovy - updated

Copying annotations between images.groovy - Two scripts to save and restore annotations using a separate file.

Create cells from detections.groovy - allows editing of base nuclei, then use those ROIs to create a cell with cell expansion

Create detection objects from annotations.groovy - Another version of creating detection objects, with a few other options (bounding box)


Force update selected annotation.groovy - Updates a single annotation in the case when the cells within it are not considered child objects.

Lock all annotations.groovy

Merge touching detections.groovy - what it says! Similar to mergeSelectedAnnotations() command.

Mirroring objects.groovy - Creating a mirror image object (or other transformations)

Object Subtraction.groovy - Performing subtraction between two objects (to create holes, for instance)

Points to detections conversion.groovy - Change point annotations into detections

Polyline to polygon.groovy - convert a polyline into a closed polygon. No holes.1

Rename annotations and modify annotation lists.groovy - Mass renaming. Creates a subset of a list and incrementally names annotations. 

Rings around an annotation.groovy - Create bands around an annotation, for example stroma within X um, 2X um, 3X um etc of a tumor

Rotate all annotations.groovy - Another transformation to rotate annotations, partial tissue alignment when overlaying a QPDATA file.

Set all TMA cores to valid.groovy - Newly added cores, through the TMA menu, will not be "valid" and will be ignored. This will fix that.

Set TMA cores to valid if tissue area over threshold.groovy - Same but runs simple tissue detection and chooses which TMA cores to set
as valid based on the area of tissue detected.

Split annotations into contiguous areas.groovy - And version 2, two ways to split annotations.

TMA-add cell measurements by class.groovy - Adds percentage by class, and cells/mm^2 to the TMA core for every existing cell class

Tumor invasion areas 0.2.0.groovy - uses the tissue border and tumor annotation to generate regions of increasing distance from tumor border

Update detections in annotations.groovy - Another version of Force update selected annotation.groovy that works for multiple annotations.

Use points to create cells.groovy - https://gist.github.com/Svidro/ffb6951e70187de5eb007290f61aea4a#file-use-points-to-place-cells-groovy

From https://forum.image.sc/t/qupath-multiple-image-alignment-and-object-transfer/35521/3
0.2.0m9
 * Script to transfer QuPath objects from one group of images to another single image, applying an AffineTransform to any ROIs.
 * This script should be run from the image you want to move the objects into, and will access all files within the Affine subfolder.
 * You must have generated Affine files first through another script before using this script.
 1. Create objects in source images.
 2. Create alignments to destination image from within each of the source images.
 3. Run this script from the destination image.
 
Script base on Pete's here: https://forum.image.sc/t/interactive-image-alignment/23745/9

 Michael Nelson 3/2020
 * All objects in the source images should be imported into the destination image.

Alignment - MultiFile Distribute to all other images.groovy

/**
From https://forum.image.sc/t/qupath-multiple-image-alignment-and-object-transfer/35521/2
0.2.0m9
If you have annotations within annotations, you may get duplicates. Ask on the forum or change the def pathObjects line.

To use, have all objects desired in one image, and alignment files in the Affine folder within your project folder.
If you have not saved those, this script will not work.
It will use ALL of the affine transforms in that folder to transform the objects in the current image to the destination images
that are named after the affine files. 

Requires creating each affine transformation from the destination images so that there are multiple transform files with different names.

Alignment - TransferObjects using stored matrix.groovy

/**
 * Script to transfer QuPath objects from one image to another, applying an AffineTransform to any ROIs.
 * Should be run from the image you want to move the objects into
 * otherImageName should be the name of the file the objects are coming from...
 * and will also be the name of the affine transformation matrix file in the Affine folder
 
 
 * The easiest way to do this is to create objects in image A, perform the alignment between images in image B
 * and then run this script from image B (destination). 
 
 
 * The script can be reworked to behave in different ways as well, for example you could
 * create an alignment in image B, C, and D to image A (open 3 different images, create the alignment to the first image
 * in each), which will give you Affine files named B, C and D. Then the objects in B, C and D could all be transferred back
 * to A, or by flipping the invert boolean, distribute the objects in image A to B, C and D. Performing the alignment to A
 * from all other images streamlines downstream mass transfers, though some of the script may need to be edited for specific cases
 * There is also a varient of the script that loops through all Affine objects within a folder and uses them to transfer 
 * objects in a loop.

Tumor invasion multiple levels m6.groovy

/**
0.2.0
 * Script to help with annotating tumor regions, chopping increasing chunks into the tumor.
 * SEE THREAD HERE FOR DESCRIPTION ON USE: https://forum.image.sc/t/reduce-annotations/24305/12?u=research_associate
 * Here, each of the margin regions is approximately 100 microns in width.
Recommended BEFORE running the script if your tumor is on the tissue border:
    1. Do have a simple tissue detection made to limit the borders.
    2. Make an inverse area, delete the original tissue, and use CTRL+SHIFT BRUSH TOOL mostly to create the border of your tumor touching the simple tissue detection edge. You can use the wand tool for the interior of the tumor, but any little pixel that is missed by the wand tool defining the whitespace border of the tumor will result in an expansion. Brush tool them all away.
    3. Invert the inverted tissue detection to get the original tissue back, and then delete the inverted annotation. You now have a tumor annotation that is right up against the tissue border.
    4. Select the tumor and run the script

Update detections in annotations.groovy

The tileExporter script you have a picture of exports tiles. Have you followed the steps to create a pixel classifier with your annotations?
I'd also recommend never running your pixel classifier on the training image, as you will not be able to retrain it later. Duplicate the image or create a new copy of the project before deleting all of your training objects.
https://qupath.readthedocs.io/en/stable/docs/tutorials/pixel_classification.html

This is also a pixel classifier, not an object classifier. I bring that up since some of your none annotations include tissue, which will confuse the pixel classifier. Also, as written, you will be creating a lot of none objects, which usually is not wanted. Better to not create the none objects at all, as described in the documentation link above.

Thank you for your help Ottenere Outlook per Android<https://aka.ms/AAb9ysg>

Hi,
I want to change some parameters in the runplugin {} line for the cell detection groovy script and parse the changes from python. How can I make changes inside the specific line in the groovy script from python?
