+===============================
+
+The required attributes of the stimulus, controlling its basic function and behaviour
+
+
+.. _eyetrackermarkercomponent-startVal:

+    
+.. _eyetrackermarkercomponent-startEstim:
+Expected start (s) 
+    If you are using frames to control timing of your stimuli, you can add an expected start time to display the component timeline in the routine.
