but do you need a registration? What space do you want the volume to be
in? If the standard FS "conformed" space you don't need a regisration (you
can specify --identity <subject ID). Or you can specify a registration
with --reg or --lta. In any case, mri_surf2vol has pretty good
documentation (thanks Doug!). Check out mri_surf2vol --help
