Have you looked at my presentation on group analysis? The slides are here:
http://surfer.nmr.mgh.harvard.edu/docs/ftp/pub/docs/freesurfer.groupanalysis.pdf
There's a very similar design on slides 23 and 24.

There are two things you can do here. One is to create your own design
matrix in a text file and pass it to mri_glmfit with the --X (instead of
using an fsgd file). If you want to stay with the fsgd, then you can
spec DODS (this will set up one regressor for MMSE instead of two).

Use mri_vol2vol, something like:
mri_vol2vol --mov ribbon.mgz --targ rawavg.mgz --regheader --o
ribbon-in-rawavg.nii --interp nearest

HI Tori,
I don't think fsgd option is available on the tksurfer or tkmedit command
line. It would have nice to load fsgd file on command line instead of
loading from tksurfer gui.

Hi Ryan,
something seems dramatically wrong as we shouldn't be missing that much
wm. Do you want to put the subject on our filedrop and we'll take a look?

Hi FreeSurfer experts,
I am a beginner of free surfer. Now I am working on my previous dataset
with new hypothesis. In this dataset, I found a ROI (located almost in
gray matter) showed significant functional difference between groups. I
want to test whether the cortical thickness is changed or not
Hi Carl,
you could read them into matlab, take the absolute value, and write them
back out again if you want, then run a glm on that. load_mgh and save_mgh
are the matlab i/o routines.
cheers,

Dear all,
for a vertex-wise comparison of the mean curvature is there a
possibility to change the signed curvature values from the preprocessed
curv.mgh to unsigned (absolute) values for the glm?
Thanks in advance,

Hi,
using version 4.0.5.
i used mri_extract_label on the aparc+aseg.mgz file to extract and convert
labels into volume nifti files, which i can view and use outside FreeSurfer.
works fine.
however, i have manually edited some surface labels, following the
instructions found here:
