AFNI Message Board

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

That sounds very unusual. Because of the unbiasedness property (whether you model the temporal correlation in the residuals or not at the individual level), the difference at the group level between the two approaches should be negligible if you only take effect estimates for group level. As a first step, could you provide the scripts for one subject as well as the scripts for group analysis?
