Hello,
I am trying to send markers to a biopac fnirs system which accepts standard LPT signals. I am using the standard go/nogo task from inquist https://www.millisecond.com/download/library/gonogo/

I would like to send markers during each stimulus during the trials and different markers based on the trial type.

Blankscreen
Verticalcue
Horizontalcue
Verticalgotarget
Horizontalgotarget
Verticalnogotarget
Horizontalnogotarget

Is there a way to define it with the stimuli so that the marker is sent at the same time it is presented?

/ items = cues
/ select = 1
/ size = (25%,25%)
/ position = (50%,50%)
