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)?
