Hi,
I have a question about the sphere registration. The registration of surface is spherical registation, so the outpput of the surface is also a sphere. When we have the inflated and smoothwm, we can convert the surface into sphere using mris_sphere, but reversely, how to convert the deformed sphere in the form of white surface or pial surface?
Also, if I want to use the surface between the white and pial surface to do registration, do I need to make the sphere myself?
Thanks,
