[Eeglablist] multiple tasks on one cnt file

Peter,

This is great, thank you. Quick follow-up.

 When trying to create a code from this for multiple participants, the
issue is that the # type for the start/stop trigger may be different for
each participant (depending on how they answered). because of the varying
place for the start/stop triggers, a code like this wouldn't work: "EEG =
pop_editeventvals(EEG,'changefield',{631 'type' 'stop_1007  Task 1
(start/stop)'});".

is there a way to get around this? maybe noting something such as if 1st
occurrence of trigger 1007, then 1007_start, if 2nd occurrence, then
1007_stop?

Thank you!

Brian
