I couldn't get either of the built-in functions to work to check the registration between two volumes which should have been the same. I also noticed that the tkregister2 wiki pagehttp://surfer.nmr.mgh.harvard.edu/fswiki/tkregister2contains no info about the command, though it does have a link to the TkRegister2 Guide http://surfer.nmr.mgh.harvard.edu/fswiki/TkRegister2Guide, which does not exist.

Hi Jason
try specifying --regheader so tkregister2 will compute the registration from the vox2ras of the two scans.
