Community-contributed modules

Usage: save the .py file to a directory, add the directory to the additional module paths in the Slicer application settings.



Community-contributed examples

Usage: Copy-paste the shown code lines or linked .py file contents into Python console in Slicer.


  • Get a MRML node in the scene based on the node name and call methods of that object. For the MRHead sample data:
  • Capture the full Slicer screen and save it into a file
 img = qt.QPixmap.grabWidget(slicer.util.mainWindow()).toImage()'c:/tmp/test.png')
    • To capture the content of a slice viewer:
 viewNames =
 img = qt.QPixmap.grabWidget([0]))
  • Capture a video of the scene rotating in the 3D view
  • To create an animated gif of the saved frames, you can use the following tools:
    • sips (Mac only) to convert single frame to GIF format (cannot save as .gif with QImage)
    • gifsicle to combine individual frames into a single animated gif (gifsicle is a command line tool, so you can batch it!)

Launching Slicer

  • How to open an .mrb file with Slicer at the command line?
 Slicer.exe --python-code "slicer.util.loadScene( 'f:/2013-08-23-Scene.mrb' )"
  • How to run a script in the Slicer environment in batch mode (without showing any graphical user interface)?
 Slicer.exe --python-code "doSomething; doSomethingElse; etc." --testing --no-splash --no-main-window
