A problem of showing up the segmentation when loading

Hard to tell from the description, but possibly you are seeing an issue like this one:

How could I measure the mandibular condyle rotation using 3D Slicer?

Probably you have an issue with the coordinate system conventions. You can read up on RAS and LPS in the forum: Search results for 'lps ras' - 3D Slicer Community You can change options when loading if needed: [image] The SlicerCMF team might be able to comment on your other questions.
