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 Sally,

What is the exact non-linear model that you want to fit to the betas? One option is to use -stim_times_IM to generate a set of betas, one per event, and then fit a model to that. That is easier than setting up a new model for 3dNLfim. If there are too many events, particularly with other conditions, then IM is not a great option.

But in any case, can you describe the model you would like to fit to?
