<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Does anyone know whether it is possible to set up parallel
port triggering for individual slide state objects, rather than for the entire
slide object, via the OnsetSignalEnabled method? I’m using a Slide
object with two states to present a visual stimulus and then a masker
controlled by two levels of a triallist object (stimulus and masker), by
changing slide states during a single “trial” (i.e., one cycle of
the triallist object). Setting the OnsetSignalEnabled method up for the
whole slide object produces two identical sets of trigger onsets and offsets
per trial, which can get confusing on the data analysis end. It would be
nice if I could get only 1 of the slide states to produce a trigger.</span></font></p>
