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,
I wonder all these output files contained 'spatially smoothed mean
Could I know that the meaning of 'spatially smoothed' ?
Are these output files difference from the output of 'mris_curvature'
I saw the values that
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.
