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

Such a scenario warrants a close look why it occurred: head motion? subject anticipation? coding mistake in stimulus timing? Just throw in an option. If you don't believe that the brain should respond at the stimulus onset time point, simply use TENTzero (or CSPLINzero) instead of TENT (or CSPLIN). However, if you do see some large amount of signal at the onset time, consider adding a regressor of 1's at those time points (or censoring them out) to account for the unexplained data variability (e.g., head motion).
