Dear FreeSurfer Team,
We are trying to run some longitudinal data using FreeSurfer 7.4.1. We have one group and 3 scans. We would like to see the changes between these timepoints. I am not sure how to proceed with the GLM because I found two tutorials.
One here is saying I should create a longitudinal qdec table including fsid-base column and years/timepoints then run mri_glmfit --osgm https://secure-web.cisco.com/12qS0acHTgwXhZDIytchwCnsXkPJ57shyJ2uQEuf0WkwB9m...
The other one is saying to do a paired analysis. This one does not include the base and years data. https://secure-web.cisco.com/1voT6D0EOLTXJrVgGSmPK-onn8JIxg74dwxqLG9An8DuChO...
How should I proceed? Thank you!
Best regards, Eszter
