Hi Aize,
great circles on the ?h.sphere should be within about 15% of the true geodesic distance. We routinely use them to estimate distances.

Hello FS Experts,
Suppose we have two points on the cortical surface (pial for example), we want to know the distance between these two point along cortical surface (not direct distance). Does FS report this kind of distance? Any suggestion will be very appreciated.
