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

Jenn,

Is this an event-related experiment? Are the fixation time points those TR's when the subject is not asked to perform a task? If so, you don't need to explicitly model those fixation time points since they are handled by the polynomials through "-polort 3" in your script, and all the results can be automatically interpreted as a contrast against the fixation.
