Hi Jidan,

there is one-to-one correspondence between each vertex on the surface (e.g. ?h.white) and that same vertex on other surface configurations (e.g. the registered sphere, ?h.sphere.reg). Does that answer your question? I'm not sure I understand it Bruce

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,
