However, in your mannual, it can only help to estimate the signal several seconds after the onset of stimuli. Thus, if I want to see the %signal change of ROIs before the onset (e.g. -2s; like baseline in ERP study), what function should I use in MarsBar? I'm looking forward to your reply! Thanks a lot!
I think you want the marsbar mailing list for this question.
I'm afraid there isn't an automated way of doing this in marsbar - but
there should be. Here I made a support issue for it:

In the meantime you could try subtracting 2s from your onsets and
rerunning the model - sorry that it not easier.
Best,
Matthew
