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

Ekarin,

Since all the three predictors are between-subject quantitative variables, I suggest that you do the following:

1) center each of the three variables properly (e.g., around their mean)

2) create four new variables - one for each interaction - and label them

3) perform a multiple regression analysis on the seven variables with, for example, 3dttest++ or 3dMEMA
