Once you know how you want things to work via the GUI, you can make them work via python scripting too. If you search this forum for keywords segmentation and python and labelmap you’ll find lots of snippets.

This might be what you need:

You can use slicer.mrmlScene.AddNewNodeByClass to create a node and add it to the scene in one step. slicer.util.loadVolume loads file as scalar volume, while ImportLabelmapToSegmentationNode expects a labelmap volume; you need to use slicer.util.loadLabelVolume instead Relative path was used for the input image. I’m not sure what is the working directory of Slicer. It is s…
