hmmm, are you sure you are using an "o" and not a "0"? And the --regheader syntax different than I thought, it requires two argments, a subject name and a template volume (if you are using the anatomical space, any of the conformed volumes such as the norm.mgz should be fine). For example, I run:
mri_compute_volume_fractions --o test --regheader bruce.dev bruce.dev/mri/norm.mgz $Id: mri_compute_volume_fractions.c,v 1.22 2015/09/14 12:25:01 fischl Exp $ sysname Linux hostname sulc.nmr.mgh.harvard.edu machine x86_64 user fischl setenv SUBJECTS_DIR /homes/4/fischl/links/subjects cd /autofs/space/tiamat_003/users/subjects mri_compute_volume_fractions --o test --regheader bruce.dev bruce.dev/mri/norm.mgz outstem test regfile (null) regtype 0 segfile aseg.mgz . . .
