Hello all

This conversation was an inspiration of the following issue I am facing now with segments:)

I have done so far an air segmentation with spatial resolution different than the master volume . Air segmentation was in resolution of (0.33X 0.33) in 2D and the master volume (MRI) is (1.96X1.96). Attached is an example

Looking forward for an answer:)

For other issues I have to downsampl the air segments into the master volume resolution. Is that possible
