If you are going to run mri_glmfit on the thicknesses in order to do
stats, then this should/could be one of the outputs. If you make two
groups in the fsgd file, then the first frame of the beta.mgh file will
be the average thickness for group1, and the 2nd frame will be group 2.
use something like:
mri_convert beta.mgh group1.mgh --frame 0
mri_convert beta.mgh group2.mgh --frame 1

Hello,
I have a two groups comparison design, and I was wondering if there
is any easy way to compute an average thickness file per group (in
order to be able to overlay mean thickness values on my average
subject). Is there an existing command or matlab function to do it?
If yes, would I also be able to do a standard deviation file using
the same command?
Many thanks,
Marie Schaer
