Hi Brian and Arvid, could you run the binary mris_euler_number on each of the relevant surfaces (?h.sphere.reg, ?h.orig, ?h.white, ?h.pial) and make sure that they all have the same number of vertices and faces, and that that matches what is in the ?h.thickness.asc file? If there is a mismatch in the # of vertices in any of the thicknesses, your results won't mean much.
