Dear staff of Cedrus Community Forums.
I am a user of SuperLab 5 and StimTracker to build and implement experiments.
I am making a experimental program in which the visual stimuli are presented with the light sensor patch to detect the time lag between the locations of the computer screen.
The light sensor patch I am using is the one equipped with the SuperLab that you can activate by ticking a checkbox in a event editor.
I would like to ask whether the presentation duration of the light sensor patch and the target stimuli can be differentiated on SuperLab 5.
For example, I would like to present a target stimulus for 200 msec and want to show the light sensor patch for the first 10 msec (onset is adjusted), remaining 190 msec stimulus without the patch being presented.
This is to reduce the number of TTL signals of each event presentation recorded via StimTracker.
I tried resolving target presentation event into two individual consecutive events (first one w/ patch for 10 msec while second one w/o patch for 190 msec, stimuli list being the same) but that led to a blink between the two events, which is a problem, so I think other measure have to be taken.
I would be pleased if I can receive a solution as to this issue.
