Hello,

I was wondering whether there is a way to assign a different intensity value on each voxel within a parcellation file (such as aseg.mgz). What I’m essentially trying to do is create a file (using the aseg.mgz file as a template) where each voxel represents a different ROI. I can think of a way to do that in Freeview for each individual voxel but I wasn’t sure whether there was a more efficient/automated way in either bash or matlab.

Let me know if the above doesn’t make any sense, and thanks in advance!

Best,

Panos
