Hi Jidan, The surface in the native space is given by ?h.white. ?h.sphere and ?h.sphere.reg provide the "mapping" of those vertices of to a spherical representation, and registered spherical representation, respectively. There are ways to get at the Jacobian of these transformations if that is what you are interested in.
