Hi,
My trial length is 3 sec, while I am using short TR of 1.5 sec (partial
brain scan). In "Specify 1-st level" template I defined Interscan Interval
as 1.5. Now, if I define durations as "0" and the onsets are the onsets of
my trials (not TRs), what is going to be my model? Will it take the first of
two TRs only? Then what is going to occur with the second TR? As far as I
understand in order to enhance my precision it is better to use both TRs
for estimation of HDR (since they belong to the same trial). What is the
correct way to define what I need?
Thanks in advance,
Vadim
