Dear AFNI users-
We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:
https://discuss.afni.nimh.nih.gov
Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.
The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.
Sincerely,
AFNI HQ

Hello,
I'm trying to run a correlation analysis between brain functional connectivity and scores on a questionaire, but I can't seem to figure out how to do it in AFNI.
I was looking at this research article, Vaghi MM, VĂ©rtes PE, Kitzbichler MG, Apergis-Schoute AM, van der Flier FE, Fineberg NA, Sule A, Zaman R, Voon V, Kundu P, Bullmore ET, Robbins TW. Specific Frontostriatal Cir

Yes, here is the table with all my data:

I am currently trying to run the following 2x2 model on a small portion of my resting state data (just 2 subjects). Each subject's data consists of a z-scored correlation map between a seed region and whole brain. I used the pipeline here to generate the correlation maps per subject:
Here is the code I'm using:
