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

Hello AFNI team,
I ran 3dREMLfit on my single subjects, to then use the coefficients and t-stats with 3dMEMA (paired contrast). The output of 3dMEMA was then used to define a mask within which I wanted to perform a statistical test that looks on how the contrast is modulated by different covariates.
To do that, within the mask, I ran 3dMVM on the coefficients obtained with 3dREMLfit, and defined my desired GLTs.
Is this legit? Or must I use 3dMEMA on coefficients obtained with 3dREMLfit? If so - how do I define GLTs with 3dMEMA?
Also, any tips on the advatages of 3dMEMA over 3dttest++ would be appreciated (I chose 3dMEMA just because the results looked a little better compared to what I got with 3dttest++, no strong theoretical reasoning).
Thanks!

Is it OK to run 3dMVM on coefficients obtained with 3dREMLfit?
