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

Dear Gang, AFNI experts and users
I have 5 groups subjects. Condition1 and condition 2 were performed for each subject in group 1. Condition 3 and 4 for group 2. Condition 5 and 6 for group 3....

The roi is with-sub variable. Contrast meant the conditions. However, the 3dMVM could not perform well and it echo about 4 possible reasons. It perform well when I change the table to this:

12517_1 generous roi_25 beta_12517_generous_x_roi_25_allrun+tlrc \
======

However, I want to let the model know the condition 1 and condition 2 were belong to one person; condition 3 and 4 were belong to another person. So how to model it ?
Thanks.
