Hi Bruce, I will try mris_sphere! But since this is a chimp average, when you
say then register it to your atlas- is this something I should do?

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

Subject: [Freesurfer] question about surface registration to an average surface
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.

The output from registration is yet another version of the subject's surface
mesh, typically named ?h.sphere.reg, with the x,y,z vertex positions still on a
sphere, but warped so that the subject's curvature pattern best aligns with the
template data.Here is the same convexity data, now plotted on the lh.sphere.reg
surface. Similar pattern, but "stretched around".
