Voxel size scale

I completed a segmentation and in the final steps when I added a scale bar I realised that the dimensions are far too big than the real ones which makes a problem with segment statistics as well. I have a voxel resolution of 72 μm so I changed the image spacing accordingly. The problem is that the image has changed but the size of segmentation stays the same. When I change it in „Specify geometry” in Segment Editor it completely lost all shapes. I would be grateful for any tip how to solve it.

You can transform the segmentation by applying and hardening a transform. You need to put the 3 relative scaling factors in the diagonal of the transformation matrix.

I have the same issue what is the module to do that?

See the link above, which takes you to the documentation of the Transforms module. You can use this module to apply and harden transforms.
