Hi Francisco,

I would use two regressors. One for the stimulus using BLOCK(5,1) --Do not use the ,1 if not all tasks have stimuli of equal durations -- and another for the response using BLOCK(2.5,1). It is better to model the response separately, but I would treat it, as you say, as a regressor of no interest.

cheers,
