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

Hmm... it seems those contingency tables only show the associations of each subject with those 6 factors, and they do not include the most informative ones about the those 6 factors: Scanner, AA, Male, BinCan, BinTC, BinDrug.

I suspect that the problem is that you don't have all the combinations available among those 6 factors. 3dMVM is picky in the sense in the sense that it requires all the combinations available with at least 2 samples (e.g., subjects). To get around the issue, try dummy code those 6 factors as 1 and -1 (assuming there are only 2 levels for each factor), and see if 3dMVM would accept it.
