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

There are 2 different ways to code stimulus timing. If it is synchronized with your TR, you can simply list it as a vector of 0's and 1's with 1 indicating an "on" period during that TR. If it is not TR-locked (your situation), you can code it with the global time in seconds (relative to the 1st volume). In case a stimulus lasts more than one TR, there are some convenient shortcuts as well. More information can be found by typing

waver -help (pay attention to option -tstim)

and at the following site (option -stim_times)
