Hi,

I just started using 3D Slicer and have encountered a problem now that I couldn’t find an answer to yet. It would be great if someone has an idea how to solve it and help me.

I started segmenting the muscles of the lower leg of a patient just to notice when almost done that the image I was using was not cropped correctly and I was missing about 5 slices that I wanted to segment as well. I cropped my nifti-image again and was able to show the same segmentation on my new volume however I cannot continue with the segmentation here outside of borders of the old volume. My question is now is there a way to transfer my old segmentation to the new volume and continue there or would I have to segment everything again?

Thank you very much in advance and for taking the time!

Best,  
Clara

This has come up a few times and we already have a ticket for this: [https://issues.slicer.org/view.php?id=4308](https://issues.slicer.org/view.php?id=4308)

Until a convenient user interface is implemented, you need to do the following steps manually:

- Switch to Segment Editor module
- Create a new segmentation
- Set Master volume (the new, larger volume)
- Switch to Segmentations module
- Import all segments from the other segmentation using Copy/Move section

Thank you very much that’s exactly what I was hoping for!
