An Add-on for QuPath to analyze Lymphoma with AI
You can find QuPath 0.5.1 for Windows or Mac (M1/M2). For more information or other architectures, visit here.
Sometimes antivirus software may react. Click "more info" and then execute, or launch the installer in administrator mode.
You need Python 3 installed. You can find it here: macOS 64-bit universal or Windows installer (64-bit).
For more information, visit the Python 3.11 page. Don't forget to activate the environment PATH!
Now that Python is installed, you need to prepare the work environment. To do this, execute the script setup_windows for Windows or setup_linuxMac for other OS. This will take a few minutes.
-
Launch QuPath.
-
Import your image (you can also create a project or import a project with an image).
-
Rename annotations (annotation names must be unique): Annotations > Right-click > Set properties > Name.
-
Select all your annotations.
-
Go to Automate > Script editor.
-
Import the Groovy file (C:\Users\user[directory]\QuPathLymphoma\groovyFile).
-
Run the script.
-
Select your working file (the default is the project folder named QuPathLymphoma).
-
Wait for file creation and model execution. The execution time will depend on the model.

The JSON created by the Groovy file will have this format:

The program currently only accepts this format.
- Sometimes the annotations are not selected correctly. Retry selecting them if the script doesn't work.
- Occasionally, a window may hide an action window. Minimize it to access the second (there are 2 action windows).
- Displaying tiles only works after data creation, so after running the Python script (you can't access the executed data beforehand).
