Hi, I want to calculate the global thickness statistics (mean +/- SD) for all my subjects. And, I could calculate the global thickness statistics by some information about cortical thickness values of each pixel. But I can’t find any files regarding cortical thickness values of each pixel. Could you suggest me how to calculate the global thickness statistics or tell me where to get the file regarding cortical thickness values of each pixel?
Thank you in advance!

Hi Feng-Xian,
the ?h.thickness files in each subject's surf dir contain the vertex-wise thickness, and mris_anatomical_stats will compute the average. Make sure to give it -l ?h.cortex.label so it only computes them over the cortial region of the surface
cheers, Bruce

If you simply want some stats on the 'lh.thickness' and 'rh.thickness' files, you can also try:
$>mris_calc lh.thickness stats $>mris_calc rh.thickness stats
