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

I'm sure Rick will chime in, but the AFNI point of view is that all the regression and filtering should be done in one step, not in two steps. That is what the 3dTproject program is for -- it will "project out" (the mathematical lingo) the nuisance regressor, including the cosines and sines for the frequencies being rejected.

Rick's super-script, afni_proc.py, can do all of the above processing, including the steps that you mention in your (parenthetical remark).
