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

You could use this type of approach:

[afni.nimh.nih.gov]

Or use 3dcalc in a similar way to having multiple ROIs on the same map. Threshold the images for significance where anything significant is set to 1 in each overlay. Then do something along the lines of: 

3dcalc -a firstOverlay+tlrc -b secondOverlay+tlrc -c thirdOverlay+tlrc -prefix combined -expr '1*a + 2*b + 3*c'

Then you can have the AFNI viewer code 1, 2, and 3 as different colors.
