That is in response to a 60 sec stimulus. The time window is the time needed to account for a very brief stimulus (ie, the impulse response). fsfast will automatically take into account the duration of the stimulus as listed in the paradigm file.

External Email - Use Caution
Hi Doug, Thanks for the advice. I think the Leite et al. 2002 NeuroImage paper can be interpreted that way. See Figure 1 and 2. http://pop.cerco.ups-tlse.fr/pdf0609/leite_fp_02_283.pdf

When you use -gammafit, it automatically sets the time window to 40. If you really want it at 80, but -timewindow before -gammafit. Do you really expect the MION hrf to last 80 sec?
