Q3) How can I access the Event and marker information?

A3) After HDR=sopen(...) or [s,HDR]=sload(...), you can access the event information through the following fields:

HDR.EVENT.TYP type of event/marker/annotation according to table biosig/t200/eventcodes.txt or the latest version from http://cvs.sourceforge.net/viewcvs.py/biosig/biosig/t200/eventcodes.txt?view=markup
HDR.EVENT.POS   position in samples
HDR.EVENT.DUR	duration of event (in samples)
HDR.EVENT.CHN	associated channel, 0 if event applies to all channels

The fields DUR and CHN might not be present if all their elements are zero.
