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

The full F-stat is indeed a goodness-of-fit measure for the regression model.

Averaging the full F-stat across the brain is probably not a good idea because F-stat is a nonlinear measure, and resulting average value is difficult to interpret. And yes R^2 is a better candidate for that purpose.
