Hi,
I am analyzing an event-related experiment, in which the onset of each event isn't synchronized with the TR. That is, my TR=2sec, but the events in the experiment begin at random times during this TR. My question is whether it is possible to create an ideal file in which each line will be defined by the **event in the experiment** rather than by the TR. Alternatively, does anyone know about another method to analyze this kind of data?

Thanks,
Ronit
