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

Let me try one more time.

So you have two models. For the first model,

Outcome/response variable (y): mental health symptoms (behavioral variable)
Predictor (x): baseline fMRI effects at a list of ROIs

For the second model:

Outcome/response variable (y): mental health symptoms (behavioral variable)
First predictor (x1): baseline fMRI effects at a list of ROIs
Second predictor (x2): stressful events (behavioral variable)

Is this accurate? If so, you can follow Example 3 for the interaction between the two predictors. Make sure that you properly center the two predictors before creating the interaction predictor (the product of the two predictors).
