Hi everyone,  
I’m using a Slicer version 4.13.0-2021-12-01 for Ubuntu18.04.  
I want to get the Maximum slicer, length and short diameter, CT value and maximum surface area of a segment with python. But I have no idea about that.

Thank you very much for your support!

I don’t understand exactly what you want to calculate for the segment using python but there are some examples in the [script repository](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#quantifying-segments) which may be similar to what you are trying to do.

Let me know if you need any more specific help and I may be able to figure it out
