Member of



/ pulseduration = positive integer or -1 to indicate a persistent signal


integer A integer value expressing the duration of the pulse in milliseconds.


This attribute allows you to set the duration of TTL pulses that are relayed from StimTracker to external devices such as EEG and fMRI controllers. If the pulse duration is not set, StimTracker will simply set the TTL port to the specified value and leave it in that state until a different value is set. The values are defined in the attribute.

See How to Control Trial Duration and Inter-Trial Intervals for more details on controlling timing of trials.
