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

We actually recommend using the non-residual data for smoothness estimation of rest data for this reason, and afni_proc.py examples generally show getting both estimates (even just for education). But fortunately, the estimates tend to be pretty similar, so it isn't usually the end of the world to use the wrong one (occasionally, it does end the world).

The smoothness of the regression inputs tends to be just a touch higher than that of the residuals, for whatever it is worth.
