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

So if all of the class_agg times go negative, then indeed, it will not read any good times from that file, which will lead to an all-zero regressor and various warnings. Those will force you to supply a -GOFORIT level (of at least 4 in this case).

But that is okay.

The bigger question is regarding the other classes, such as Mean_anticipation_agg. The timing file for that class shows both an amplitude modulator and a duration modulator. Do you intend on that? It is okay, but then the stim type would be AM2 rather than AM1. It looks like that applies to most of the classes.

Is AM2 what you want (i.e. do you want an amplitude modulation regressor)?
