External Email - Use Caution Sorry for bothering with more questions!
I am getting an error saying , mri_compute_volume_fractions: could not load registration file from identity.nofile And my command is, mri_compute_volume_fractions identity.nofile mri/aseg.mgz test and if I try to give in this format which the documentation says, mri_compute_volume_fractions [options] --o <outstem> --reg <regfile> Am I going wrong somewhere?

The output stem is whatever you pick - it will be prepended to the files that are written with the volume fractions. cheers Bruce On Wed, 25 Apr 2018, Srinivasan, Dhivya wrote: > External Email - Use Caution > > Hi, > > I would like to get CSF/GM/WM segmentations from aseg.mgz or in other words > from labeled brain.
