You can map the curvature from fsaverage to the individual (or reverse) and then load both on the surface to see if they agree. I think that CVS will/can save intermediate registrations, so you might check those to see if the problem is cropping up at a particular step.

Dear Doug,

thanks for the response.

Talairach registration seems OK.

I am not sure, how to check surface-based registration. I have tried to look at subject's ?h.sphere.reg (with ?h.curv loaded) and ?h.sphere of fsaverage overlaid. But I am not sure if it is a correct way to do it: the spheres even do not spatially coincide (screenshot).

Regards,

Antonin

I'm not sure what happened. Have you checked the surface-based
registration? Also check the talairach reg.
