Dear @lassoan,  
Thank you for your quick reply. I did follow your recommendation in a previous post, [https://discourse.slicer.org/t/how-can-i-convert-an-rtstruct-to-an-nrrd/539/2](https://discourse.slicer.org/t/how-can-i-convert-an-rtstruct-to-an-nrrd/539/2), and I was able to save a 4D volume. The problem is we can’t reference the CT volume, and the number of images doesn’t match the number of masks, a necessary condition for PyRadiomics. Exporting to a file in the segmentations module does not save overlapping segments but provides the ability to reference a volume. I will try the slicerio Python package as you recommended since it seems very promising.
