Hi, new to slicer and working on a dicom workflow. I notice that importing my dicom ct and segments look fine in dicom apart from a body rind and couch roi.

I then export the ct and contours in dicom to file.

I then load them and many contours look different/wrong and cut in all views. When i try to edit the contours or change 2d visibility to binary label, the computer seems to struggle and freeze… help please thanks!

if its just a visual thing thats fine but if someone needs to edit etc it freezes/crashes which seems bad. might be similar to topic [Loading DICOM CT+RT Structure is incomplete - Support - 3D Slicer Community](https://discourse.slicer.org/t/loading-dicom-ct-rt-structure-is-incomplete/21696) but is there anything else i am missing? thanks

I now see I need to set binary label before Dicom export which looks better upon re import ! My follow up question is if anyone know how to set source (yellow star) to be binary label via script? I can see command for create but not set source? This would be useful to automate this step for me thanks
