Dear FreeSurfer,
In the stats files (e.g aparc) there are also statistics for the "integrated rectified mean curvature", "integrated rectified gaussian curvature", "folding index" and "intrinsic curvature index". To what kind of properties do these measures refer and which one is advised to be used?
Many thanks! Heidi
Hi Heidi
it's hard to say which one should be used - that is really dependent on your biological hypothesis. The "index" calculations are from David Van Essen paper. Sorry, I don't have the ref handy. The "integrated rectified" ones are just taking the absolute value of each, then summing them up over the surface.
cheers Bruce
