I am having some problems with 3D Slicer hanging when trying to perform ‘harden transform’ on large segmentations.
Specifically, I have some whole body PET/CT images with associated segmentations. If I create a simple linear transformation and apply it to the CT and PET volumes and segmentation, all is fine. When I use the harden transform button, everything goes as expected for the two volumes. However, when I click it with the segmentation selected, 3D Slicer hangs and eventually needs force quitting.
Is there any way that I can try and debug this to determine what the issue might be? I have tried using the python interface to harden the transform, but with the same result. I’m not sure how to get any more fine-grained knowledge of what is going on under the hood.
This is in 3D Slicer 4.10 and 4.10.1 on MacOS.
Please let me know if you need any further information.
