Hi Alain,
You probably do not need to get caught up in the
differences between GAM(15) and BLOCK4 and 5.
Consider plotting them in the way show at the
bottom of "timing_tool.py -help_basis". With a
4 s TR and block events, the difference should
not be important.
I am a little concerned with your adding the
average time to peak to the event times. That
is part of the BOLD response in those basis
functions. What sorts of peaks are you adding?
