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
Cheers Bruce

External Email - Use Caution Hi there
I have a bunch of labels on individual subjects and would like to register them to an average surface that we have created here at the MNI. 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
