Hi Mark
for mri_ca_normalize all the optional arguments (prefixed with a dash) must come before all the mandatory ones. Also, you shouldn't give it the mri directory - give it an input volume (like nu.mgz).

Hello, I am currently having some difficulties with the mri_ca_normalize command. I am attempting to create a normalized volume file using an input brain with the following command:
mri_ca_normalize /Volumes/Wong_Lab/CochlearImplant/UNC_NiFTI/infant-neo-mgz/mri/ -seg /Volumes/Wong_Lab/CochlearImplant/UNC_NiFTI/infant-neo-mgz/mri/seg.mgz/ /Applications/freesurfer/subjects/CMH-7259/mri/transforms/talairach.lta /Volumes/Wong_Lab/norm.mgz
However, I am getting an error that my seg.mgz file could not be read:

I don't believe it is a permissions issue. Any ideas?
Thanks,
