In continuation to the question I asked previously, I have ~300 PET/CT images of head and neck cancer patients got from TCIA with its RTSTRUCT. The region of interest is different in each case eg: GTV, GTV\_67.5Gy, GTV\_70Gy. I wish to extract features from these ROIs(from manually segmented images) and also from the ROIs obtained by trying a different segmentation method on these images(both PET and CT). Is there a way to automate this task using Python script or so? It would have been a time saver. I found something like this here[[Is there a way to build a macro/script out of segment editor steps? - #5 by pieper](https://discourse.slicer.org/t/is-there-a-way-to-build-a-macro-script-out-of-segment-editor-steps/4170/5)]  
Thanks
