Hi FSl users,
I'm new at FSl and try to model an event related fmri experiment, where different conditions were stimulated for 140ms with reaction time window of 1260 ms (TR: 2 s).
Now I try to model this with FSL and red the manual, which said to use custom modeling with three columns (1: onset, 2: duration, 3: 0/1) with one row for each volume. In this forum I found only examples with durations of seconds, which is not possible for my experiment. Now I want to know
a) if it's possible to model more than one stimulus within one volume (e.g. onset1: 7.0 duration1: 0.14 toggle1: 1; onset2: 8.4 duration1: 0.14 toggle1: 1; both are for volume 5
b) if the duration can be a fraction of one second
any help or advice is welcome,
thanks in advance,
Stephan
