Adjusting trigger duration

[Don.Rojas at UCHSC.edu]

I'm having trouble figuring out how to adjust trigger duration when
using the OnsetSignalEnabled property of a stimulus object.  I do not
want the trigger duration to last the entire duration of the stimulus,
which is what you get when you set the OffsetSignalEnabled property.
For example, if I have a stimulus with a 200 ms duration, I'd like the
trigger to be about 50 ms, starting at the onset of the stimulus.  Is
there a way to adjust this without resorting to doing all the triggering
in a separate in-line object?
