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

> I want to calculate the anger+fear activation map but I am confused how to average this

Do you get the average effect between anger and fear at the subject or population level? At the subject level, if you just want to get the effect estimate, do

3dcalc -a anger -b fear -expr “a+b” -prefix ...

If you want to get both the average effect and its statistical evidence, you would have to achieve that with -gltsym by running 3dDeconvolve with the option -xrestore
