Hi Trisanna Can you run mris_sphere on it to create a spherical surface? You could then register that to our atlas using mris_register. You will need to create a bunch of files that we expect though like ?h.curv, ?h.sulc, etc... You might also need to specify a volume, but I expect any conformed one will be ok

So, this average has not gone through recon-all and there are no freesurfer recon-all files associated with it. There is no volume associated with it to run in recon-all. According to the instructions for mri_surf2surf I need the sphere.reg file, which is generated during recon-all. I wonder if there is a way to undergo surface registration in my situation? I found the following documentation, but this seems to be for creating a new average. I have the average already.

Similar pattern, but "stretched around". surfer.nmr.mgh.harvard.edu Thank you, Trisanna -- Trisanna Sprung-Much, PhD Research Associate McGill University Montreal Neurological Institute
