Try using mris_preproc with "--meas curv". Create a list of your subjects in a text file which you then pass with the --f flag. The output will be all the curvs from your subjects stacked together. You can then use mri_concat with the --mean option to get the mean, or the --std to get the standard dev.

Hi Thomas,
you can specify -s <condition #> to generate means and variances, but I'm pretty sure Doug has something more up-to-date to do this.

Hi,
I am using mris_average_curvature to create an average thickness map across subjects (registered to fsaverage).
The command line I am running is:
mris_average_curvature lh.thickness lh sphere.reg subj01 subj02 .... subj20 outputfile
This produces the average, but my question is if there a way to also create a measure of variability at the vertex level from that group, e.g. the associated variance or standard deviation?
Thanks, Thomas
