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

GAM is typically used for event-related experiments. If you want to specify the duration of the stimulus, use BLOCK(d,p), where d and p are the duration and peak respectively (e.g., BLOCK(1,1) in your case). However, with a duration of 1 second, GAM (without specifying the duration) should be good enough if your TR is around 2 seconds: such a short duration (relative to TR) won't make much difference.
