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

Regarding the modeling of the HRF from the iresp output, you can look at that output several ways.

1. Simple statistics - onset, offset, duration, std. dev., mean with 3dTstat.
2. Delay - 3ddelay
3. Model with specific function - 3dNLfim. You may use your own model or one of the ones provided with AFNI. A two-variable model can be passed through an environment variable with the Expr2 model. Otherwise, you can choose an existing one or write your own.
