Hi John, you would make the event last long enough to encompass all the
subevents. It might be a problem for optseq if you need to cue the
subject as to when to perform each subevent.

Hi all - I'm trying to design my first event related experiment,
and I'm having trouble figuring out how to best optimize the
design...wondering if you have any insights:
I have two conditions (milkshake and water).
Each condition has several events in order: Participants get a squirt
of milkshake (4s) then swallow (jittered?) then a rinse of water (no
interest) then swallow (jitter again?).
In the other condition, they just get a squirt of water and a swallow.
In order to model all of this, would I need to put in every event
that's taking up time as an event, and then just do an event contrast
comparing the two conditions of interest (receipt of milkshake/water)?
Or would I make the "events" be long enough to encompass all the
actions that are taking place during that event (even though I'm just
interested in the first 4s when the person is receiving a taste)?
thanks for any tips.
