Hi 3D Slicer Community,

I’m new to 3D Slicer and still learning, and I have a few questions.

1. After performing an elastic registration, should I harden the transformed CBCT using the “Transforms” module, or should this be done from the “Data” module?

2. When I save my data and reopen the scene, I don’t get the same results.
Is there a recommended or specific way to save all transformed volumes and segmentations to ensure everything loads correctly?

3. After applying an elastic transformation, how can I extract the deformation matrix or deformation field?
I would like to quantify the deformation if possible.

4. Finally, is there any method other than “Segment Cross-Section Area” to compare bone gain before and after grafting?
I’m looking for reliable ways to quantify volumetric changes.

Thank you very much for your help.
