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

You may be able to use stim_times_IM with a fixed-shape HRF (e.g. GAM) and get the amplitude measure for each trial. One previous post that may be helpful [afni.nimh.nih.gov]

[-stim_times_IM k tname Rmodel]                                        
   Similar, but each separate time in 'tname' will get a separate      
   regressor; 'IM' means 'Individually Modulated' -- that is, each     
   event will get its own amplitude estimated.  Presumably you will    
   collect these many amplitudes afterwards and do some sort of        
   statistics or analysis on them.
