Hi AFNI experts,
I'm running amplitude modulation analyses, but at the group level I just want the overall main effect (e.g., I have no contrasts or conditions). I have been unable to find any tutorials that go over setting up group level analyses without contrasts (probably because it's not common!). When I run it with the following script, not specifying any glt, I simply get the Intercept F output. All I'm looking for is a group level effect which combines across each subject-level AM analysis (#1 coef) below. Thank you!
