Hi Bruce, I am still confusing about my subjects'recon that I still doubt my skill on detecting the topological error. Therefore, I practice on the FStutorial data and run the mris_euler_number on the "topo_defect_before" to see what happens. The result returns me with 0 holes for all ?h.pial, ?h.white and ?h.inflated.
Can you help me with this problem.
