Create an indipendent volumeNode for an organ obtained after segmentation

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 which does something similar operating directly from a segmentation MaskVolumeHistogramPlot.py
