Hi Freesurfer team,
I'm trying to run a GLM analysis with three groups (Controls, MCI, AD) with 0 covariables at the moment, but I would like to add two eventually. I've been following the tutorial on this link: https://surfer.nmr.mgh.harvard.edu/fswiki/Fsgdf3G0V, and when I write the command it says ''cannot open g3v0.fsgd for reading''. In my /subjects/fsgd file, there is my fsgd file, and my contrast file. Am I missing an additionnal file or something? Is the format of my files correct? If it can help, here's what my fsgd file looks likes: GroupDescriptorFile 1 Title OSGM Class Control Class SCD Class MCI Variables Input 3431566 CTL Input 3514091 CTL Input 4051959 CTL Input 4344061 CTL Input 4557550 CTL Input 7060373 CTL Input 7274924 CTL Input 7308293 CTL Input 7424803 CTL Input 7459501 CTL Input 7543023 CTL Input 7661810 CTL Input 8069157 CTL Input 8330218 CTL Input 8656527 CTL Input 8875385 CTL Input 9296157 CTL Input 3025432 SCD Input 3494204 SCD Input 3702154 SCD Input 3708747 SCD Input 3865361 SCD Input 4316663 SCD Input 4509950 SCD Input 4548020 SCD Input 4893763 SCD Input 5381177 SCD Input 5477234 SCD Input 5522727 SCD Input 6121388 SCD Input 6168985 SCD Input 6258913 SCD Input 6274286 SCD Input 6334263 SCD Input 6417837 SCD Input 6427603 SCD Input 7435733 SCD Input 7485585 SCD Input 7712552 SCD Input 8827943 SCD Input 8980899 SCD Regards, Nick Corriveau-Lecavalier, B.Sc.
