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

In your case with 3dttest++ for group comparison, it should give you three results in one analysis: one group comparison and two individual group results. So do you still see strong activation for one group in the same 3dttest++ output? Could you post your 3dttest++ script?

The pooled vs. unpooled issue usually should not make a big difference. How different in terms of the number of subjects across groups?

Conjunction analysis is only used as a post hoc method to obtain common activation areas, which does not seem to apply to your case.

Gang
