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

There might be 3 reasonable possibilities:

1. Move the trials without a modulator to a different regressor class.
2. Assign an average response time to such trials (so they do not affect the modulation beta).
3. Assign a maximum (but reasonable) response time to such trials (because that seems more natural based on the task).

Which to do depends on the task and the circumstances of a failed behavioral response. Was the subject trying but just too slow? What the subject not paying attention?
