!Complex scripts
Set of scripts created to help the workflow with (primarily) IF images
TOC
Affine transform objects between images.groovy - used with the Align images experimental tool in v0.2.0m1
Background staining check - Takes annotations, expands an area around them, checks the staining level in that area,
then deletes all expanded areas and any original areas that violate some condition. Can help check for staining artifacts.
Classifier with GUI.groovy - User interface based macro to simplify classifying many possible channels. Also generates all
possible combinations of base classes (double, triple, etc positives).
Classifier with no GUI.groovy - Same as above but streamlined for use in a script, with no user interaction.
*Added Detection based versions of both above scripts which should work for tiles.
Invasion assay or tumor adjacent area.groovy - Creating areas of increasing distance from the tumor annotation border. Use negative
values in the annotation expansion for invasion assays.
Lipid detection and measurement.groovy - Detects lighter areas within your tissue area and creates detection objects with measurements.
Multiple cell detections.groovy - Set of scripts that allow the user to run one cell detection, store those results, run a second cell
detection, and then import the results of the first. Useful when one set of Cell detection variables does not accurately detect all
of your cells.
Positive Pixel scripting for QP 1.2.groovy - Demonstrates ways to succesfully use positive pixel detection to handle difficult staining.
Positive Pixel scripting for QP 1.3.groovy - Same as above but modified for alterations to positive pixel detection in 1.3
Step 1 through Step 4 - Part of a workflow for semiautomated generation of very high resolution cells. User defines the cytoplasm.
https://groups.google.com/forum/#!msg/qupath-users/ehxID096NV8/U7n5_CNABwAJ
Tissue detection (for workflow) - Two scripts that mimic Simple Tissue Detection from QuPath, but give more channel flexibility when
working with fluorescent images. Normally QuPath will only use the first channel for tissue detection, while this will let you choose
the balance between channels that works best for you. Workflow version removes the GUI.
https://groups.google.com/forum/#!topic/qupath-users/4g26bLOC_CE
Tumor Region Measurements - Script is from Pete and can be used for measurements in and around a tumor.
https://petebankhead.github.io/qupath/scripts/2018/08/08/three-regions.html
Updated Jan 2019 with Classifier scripts to make it easier to... well, classify. https://groups.google.com/forum/#!topic/qupath-users/LMxYihQMvTw
Updated Dec 2018 with a Tissue Detection script that can act in a similar (rough) fashion to simple tissue detection, but has the
advantage of allowing the user to choose and weight channels. This makes it possible to look at specific areas within tissue
samples, even in 7-8 color images. See here for examples and an explanation: https://groups.google.com/forum/#!topic/qupath-users/4g26bLOC_CE
