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

Maybe I am not quite following what the input is. Is this just the regression of phase 2, the last 4 runs? And in phase 2, you want the model b1*S1 + b2*S2 + b3*S1*S2? Or is that model supposed to span all 8 runs? That aspect is not quite clear.

In general, it is more appropriate to run a single complete regression than to project nuisance before a secondary one.
But ignoring that, I just want to clarify what the input to the regression is (4 runs (and which) or 8).

Thanks,

- rick
