Hello FreeSurfer users,
I am using FreeSurfer version 6 with the latest dev version of freeview on a
Linux machine. When I load a surface into freeview with a color scale, I notice
the scale does not correlate with the values in the surface. The min

Dear experts,
I was hoping on examining the correlation between thickness and cognition
within one group only and visualizing this using the command line stream. For
my analysis I was planning on using cognitive scores that are adjusted

Hello,
I'm using freesurfer ver 6.0.0.
If there are defects with the pial surface (i.e. the pial surface does not
cover all the gray matter that it should), can you also assume that the
eTIV has not been estimated incorrectly, or do pial surface inaccu

Hi Doug,
We actually do want the voxel-by-voxel results. Could you please give
details on how we would do that? Specifically, would we need to use the
command line to run the Welch's T/F or would we extract values for each
voxel and put them into anot
Run mri_glmfit on both groups separately, using a contrast to compute the mean
of the group. This will create two directories, one for each group. In each
directory, there will be a variance measure (rvar.mgh) and a mean of the
contrast (contrast/gamma.mgh). You then need to compute the welch's
The eTIV is unrelated to the pial surface, so you do not need to edit to get a
good eTIV.

sorry, at one point you say that you are planning to use cognitive scores, then
in the next sentence you say you don't want to use them. How would you find an
association if you don't use them as a covariate?
