I segmented some structures using a cropped volume from a bigger one. I realized that I wanted a bigger volume so I cropped the original again. However, the segmentation I had is not working in the new area.
I can’t use tools outside the original area (green). How can I fix this? I tryied to change the master volume but if I do “mask volume” it does not work. I tryied to create another segmentation node and copy the segment but nothing. I’m becoming a bit crazy.

If you can provide step-by-step description (or screen capture video) of the unexpected behavior then we can investigate. In the meantime, after your change the segment geometry, you may try to apply smoothing to all segments to force using the new geometry.
1- Open volume. Let’s call it volume.
2- Crop volume to obtain a smaller one. Let’s call it smallCroppedVolume.
3- Segment croppedVolume. Here I have several segments.
4- Crop volume again but this time we obtain a bigger one, bigCroppedVolume.
5- Try to segment bigCroppedVolume. Realize that tools only work on the area of smallCroppedVolume.
6- Change geometry and master volume to bigCropppedVolume. Now paint tool works but if I try to mask bigCroppedVolume, then it does not work.
It seems to work when applying smothing. Is there a way to apply smoothing and then undo the results (with code), so I don’t want to modify the segments.
