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

Hi Tom,

I find it helpful to create separate thresholded maps using 3dmerge(-1clip). Then combine them in a single brik using 3dcalc. Voxels activated in both maps will have a value of 3. Unique map 1 activation has the value of 1 and unique map 2 activation has a value of 2.

3dcalc \
-a mask1+tlrc \
-b mask2+tlrc \
-expr "bool(a)+(2*bool(b))" \
-prefix binarymask

Then, open this binarymask in the afni window, click positive with 4 colors, and you'll see the "big picture".
