Adjusting trigger duration

[Tony Zuccolotto]

Donald,

 

The use of another object is about the only way to do this currently (we
hope to add a PulseDuration property to the architecture at sometime in
the future), although this doesn't have to be an Inline with script (at
least not in the scenario you are describing).

 

You just need to set the Stimulus duration to 50ms and then follow it
with a Wait object of 150ms.   If you have a response enabled on the
Stimulus object then just set the Time Limit property to the total
duration you want the response enabled for.   This should allow you to
get what you want w/o script.   

 

Thanks,
Tony

Subject: Adjusting trigger duration

 

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?
