Thanks, first of all. I tried with the following scripts, but ended up with an error. I am not sure which format or file is required for the --volreg.
# mri_surf2surf --s FS --hemi lh --sval-nxyz pial --tval ./ttt.mgz # mri_surf2vol --surfval ttt.mgz --hemi lh --volreg mri/transforms/ talairach.xfm --outvol ooo.mgz --template mri/T1.mgz gdiagno = -1 regio_read_register(): No such file or directory Error reading inplaneres from mri/transforms/talairach.xfm Thanks, Seok On Mar 9, 2011, at 2:00 PM, Douglas N Greve wrote: > Try using mri_surf2surf with the --sval-nxyz.
