[Eeglablist] extracting epochs with needed events, eeg_context?

[Ольга Протасенко]

Hello, everyone!

The task is:
The user selects in GUI an event and then, in the EditText puts in boolean logic expression. 
For example,  "1, 8 (100,300)", 
which means that we need to extract those epochs that corresponds to: event 1 is followed by event 8 in duration of (100-300 ms from the event 1).

I've founded eeg_context function and tried to use it, but failed.

Thank you for help.
