Which way do you want to go? Convert FS volumes back into the native space or the other way around?
To convert native space vols into FS, run something like:
tkregister2 --s subjectname --mov mri/orig/001.mgz --regheader --reg reg.dat
This will bring up both the conformed and nonconf volumes, and there should be an exact registration. Once you're confidient of that, you can add --noedit in which case it will simply produce reg.dat without bringing up the gui.
Then you can run
mri_vol2vol --mov anynativevolume --fstarg --o anynativevolume.inconformedspace.mgz
The new volume will be in the conformed (orig.mgz) space.

Hi, I have a few datasets I ran in freesurfer that were originally in 181x217x181 format. As usual, these were converted to 256^3 early in the process. Basically, I'd like to run some comparison stats between the freesurfer volumes and the same subjects run in a couple other programs (that are still 181x217x181), and was wondering what the best way would be to reobtain an exact overlay between the two.
Thanks,
