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

It's hard to pinpoint the reason for the failure without direct access to the data. What AFNI version do you have? Not sure if updating the most recent version would help.

A couple of comments that are unrelated to the error.

> -model ‘A*B*C*D+E+(1+A+B|Subj)' \
> -qVars ‘C,D,E’ \

1) Make sure that all the 3 quantitative predictors C, D and E are properly centered. The default is mean centering.

2) If the interaction between C and D is of interest, I suggest that you create a separate variable, for example, called F. Center C and D first, and let F = C x D. Then, set the following:

-model ‘A*B*C+A*B*D+A*B*F+E+...' \
-qVars ‘C,D,F,E’ \
-qVarCenters '0,0,0,...' \

3) Are A, B, C, D and E within- or between-subject variables?
