Hi Tony
you can do that but it won't measure the distortion induced by the sphere mapping itself.

Hi,
I'm trying evaluating the distortion for each subject from their native space to fsaverage atlas space. Is it a appropriate measure to compare ?h.sphere and ?h.sphere.reg? I assume that by comparison, I may get the how each vertex warped during the registration? Thanks!
Best,
Tony
