Hi,
How do you compute the cortical thickness for each structure as listed in the ?h.aparc.stats file? Is it equal to the thickness at each vertex averaged over all vertices within the structure?

Hi Ed You should probably weight each vertex by surface area, but the answer won't be too different from a straight average Cheers Bruce
