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

Yes, the issue in the first point would arise because of the separate motion regression.
It would be more correct to orthogonalize the regressors of interest with respect to motion and polort, whatever is in the initial regression.

But really, what is the benefit of running 2 regression steps (projecting nuisance before computing betas)?
