you should be able to generalize two groups/one covariate and/or four groups one covariate. don't use gender as a continuous covariate. Make sure to normalize your covariates

Hi, 
TKS for helping me!
I looked at the examples of the FSGD files, but I believe that my data doesn't fit. I've three groups/three factors at three levels (LR=1, HR=2, MDD=3) and 6 covariates (gender, age and global brain measure). 
I don't know if I was clear in my explanation.

look at the fsgd examples to see if any fit your situation. Note that the input needs to be something like
Input    310211    LR 1    15,5    2,678785    645292,6651    152275,2   
ie, "LR" instead of "1", etc
using commas (,) instead of points (.) may cause problems

I'm sorry!

Hi Freesufer's,
I need to run a group analysis but I don't know how to do it, the error always appears (print below). There are 3 groups ( risk_group) that I would like to insert as a class (LR = level 1, HR = level 2 and MDD = level 3) and I would like to control for sex, age and total brain measure. Please, if anyone can help me understand what I'm doing wrong, I'd really appreciate it. 
The FSG file is attached
Thank you.
