ShowPlay Reference Manual, Chapter 4 (StimulusEvents): Start
START refers to the onset time of the stimulus (in milliseconds) relative to start of stimulus presentation or the most recent RESET stimulus. Stimulus presentation starts START_DELAY ms after the start of the paradigm (where START_DELAY is a parameter variable described in “Paradigm parameters” above.) For fMRI the start of the paradigm is usually the time of acquisition of the first image (i.e., excluding DISDAQS).
