You can get thickness with aparcastats2table
regions, but not that
measure of mean thickness for the hemisphere. Could I be missing
something?
thanks

Hi,
I was wondering what should I use as an average of cortical thickness for
the whole cortex.
The aparc.stats output gives a value of Mean Thickness for each
hemisphere. But this value does not coincide with the one I get if I
average the 34 variables from aparc.stats. Do you know why?
thanks
Hi Daniel
the parcellations are not uniform in size, and therefore the average of
them will not be the same as averaging over the cortex.
cheers

Please, is there any automatic way to extract this Mean Thickness values
for lh and rh for a big group of subjects? As for example aparcstats2table?
thank you very much

You can get thickness with aparcastats2table with the -m thickness
option. This gives you a measure of mean thickness for the hemisphere as
well.
