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

When looking at a contrast between two variables within a group (2-way ANOVA), and there is both positive and negative activation, how does one intrepret the results? For instance, can one assume, when setting the intensity scale at '12,' that the red activation clusters are representative of the dominant variable and that the blue activation clusters are representative of the other variable?

How does AFNI treat positive vs. negative beta values in a contrast?
Thanks!!!!!!!
