[Eeglablist] Problem with markers the events and extract epochs

[Makoto Miyakoshi]

Dear Jason,

Sorry I could not get back to you timely.
There is nothing I can help you in this situation as a volunteer. The
official advice would be 1) you post it to eeglab bugzilla
https://sccn.ucsd.edu/bugzilla/enter_bug.cgi 2) you contact the vender.
