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

Hi Wil,

-TR_times sets up the time grid size when you output the impulse response function with option -iresp and the associated standard deviations with option -sresp, and would not have effect on anything else. And it does not have to be the same as your TR (and can be finer).

Your setup with -stim_times seems fine to me. It is not expected the result from 3dDeconvolve would be exactly the same as the one from SPM because there are quite a few things different in terms of pre-processing and modeling strategy. But how different are they and in what sense?
