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.
