Hello, I'm working on group analysis in fMRI activation using FSFAST. I tend to test whether any significant changed in fMRI activation within group across two time points ( pre-training vs post). I ran first level already. I still confuse about the concat data and the mri_glmfit command. Here are the command lines, I'm wondering if it runs exactly what I want it to do.
