Sorry to be slow to reply, I am just catching up with my mail after
being away for a couple of weeks.

Event-related averaging is best done with the FIR model - see the FAQ
for more details.  The FIR model can be specified in your design as
the event basis function, or you can use the event responses interface
in marsbar.   % signal change is another option on the results menu.

Best,
