Good morning everyone, after applying the ‘totalSegmentator’ module, I obtained all my abdominal organs segmented.  
How can I now associate, for example, only my ‘liver’ object with a new volume node so that I can manage and work on it independently, without working with all the other segmented structures?  
How can i do this operation also with a python script?  
thanks a lot

Take a look at the Mask Scalar Volume module, it should provide exactly the functionality you need. Also, here is a python script linked from the [script repository](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html) which does something similar operating directly from a segmentation [MaskVolumeHistogramPlot.py](https://gist.github.com/lassoan/2f5071c562108dac8efe277c78f2620f)
