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

Using -stim_file means Dirac basis functions "1" times in the input file (which must have the same TR as the input dataset). Only -stim_times offers a choice of basis functions; however, -stim_times requires a list of times rather that a list of 0s and 1s: -stim_times input is NOT locked to the TR of the input dataset.

If you wish to use -stim_times, Rick Reynolds wrote a Python script to convert a 0-1 file for -stim_file into a list of times for -stim_times. Documentation for this script can be found at

The list of basis functions and other information about using -stim_times can be found in the various documents under
