Yes, just specify --regheader subjectname instead of a --reg

Hi all,

Usually when I want to map volume data to the fsaverage surface, I use mri_vol2surf with a registration that transforms the volume into the space of the subject's orig.mgz and with --trgsubject set to 'fsaverage'. Currently, I have some volumes that have already been transformed to the subjects' orig.mgz space that I want to bring to the fsaverage surface. Can I still just give mri_vol2surf the same registration that I used to transform this volume in the first place, or will this try to re-apply that registration and end up in the wrong space? If that's incorrect, what's the best way to go about doing this?

Thank you!

Best, John
