Hello!
I have a bunch of cranial endocast saved in obj form. I want to try to section of the cerebellum region, and I think this should be possible in maybe segment editor. However, since the obj is mesh model, i cannot edit it in segment editor. How could I get to meausure the surface area and volume of only a section of the endocast?
It may load as a model node, but then you can convert it to a segmentation node and do all the segmentation-related things with it like segment editing and segment statistics.
You can import directly to segmentation also, rather than converting: Segmentations — 3D Slicer documentation
You can edit surface meshes (e.g., OBJ, PLY, STL) using the ‘Dynamic Modeler’ module: Slicer/Docs/user_guide/modules/dynamicmodeler.md at main · Slicer/Slicer · GitHub. You should be able to select most of the cerebellum this way.
