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

Thank you very much for the clarification! I ran my code successfully and it seemed to work.

I was reviewing the 3dMVM post and I saw that for the gltCoding it indicated:

"...for example, the following 'Group : 1*A -1*B & 1*A -1*C' tests the main effect across the 3 groups A, B, and C. Important Note: this option is only valid for
a hypothesis that involves between-subjects variables. For an F-test involving a within-subject variable, use -glfCode with 3dLME instead

In my ANOVA I have one between factor and 2 within-subjects factors. When I listed my glts I had indicated the main effects of each factor and their interactions. From the posting above, it would seem incorrect for me to use 3dMVM and get main effects for the within-subject factor? I am just wondering whether this is the case, or whether this would be okay.

Thank you in advance for your help.
Tamara
