Dear Bruce Fischl, Thank you for your explanation.
I think I could not yet fully understand the 'curv' files. After processed this command, recon-all -s <subject> -i <input file> -all the output files were follow as, surf/?h.curv surf/?h.curv.pial surf/?h.inflated.H surf/?h.inflated.K I wonder all these output files contained 'spatially smoothed mean curvature'. Could I know that the meaning of 'spatially smoothed' ? Are these output files difference from the output of 'mris_curvature' command? I saw the values that stats/?h.aparc.stats and stats/?h.aparc.a2009s.stats contained the 'integrated rectified Mean curvature' and 'integrated rectified Gaussian curvature'. I wonder these values were if the average curvature of vertices in each region, or other computed values using different atlas parcellation level. I appreciate your help. Best Wishes, Han.
