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

I'm not so sure what you mean by removing the effect of the behavioral measures. If you put a variable in a model, the effect from that variable is accounted for. If that's not what you're looking for, what is it???

Aside from the question you're asking, actually when I take a close look at what you said before, I feel something is not quite right. You have 8 blocks from each subject, but is this a group analysis with multiple subjects? If so, 3dRegAna is not the right tool for that.

You analyzed each block as a separate regressor at individual level? Was the behavioral measure acquired at each block level?
