So you are trying to predict the neuropsych battery from brain
measurement? This is not how mri_glmfit is usually used, but it is just
a GLM so it is possible. You'd have to set up a table for the --table
input. You can try running asegstats2table to get an example table, then
you'd just set up

Hello,
I am working on a project using FreeSurfer, and I am trying to set up a
whole brain group analysis. However, I am not sure how to set up the FSDG
files, etc., as my dependent variable is not a cortical measurement. My
dependent variable is a neu
I think that contrast computes Female-Male regressing out Dx and age. If you
want HC vs MS, then use
-0.5 -0.5 0.5 0.5

Hi Freesurfer Team,
I am performing an analysis on 23 HC and 26 people with MS and I would like to
perform the stats appropriately. I would like to control for (or regress out)
age and sex. Therefore, I created my FSGD file which has 4 classes (HC_Ma
Hi FS experts,
I sent a similar question to this last week but I never got a response. Any
ideas would be very much appreciated!
I have gone through the Group Analysis tutorial
(https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/GroupAnalysisDng) and am

yes, I think so. Maybe others can comment.

Not necessarily. It could have been in the FS analysis. You can run
mri_glmfit with --kurtosis (a hidden option). This will create a

Hey Doug,
I have run a group analysis on my data with two different ways. (The input is
cortical thickness.) In the first analysis, I specified 4 groups
(Diseased_Male, Diseased_Female, Healthy_Male, and Healthy_Female) whereas in
the second, just two groups (Diseased, Healthy). One of the comp
