[Eeglablist] rereferencing and epochs

[Skotara]

Hello everybody,

sorry for my basic questions. I am a beginner in eeglab and try to 
figure out some basic functions in eeglab. I like to adjust them to my 
needs.

Is it possible to rereference the data using one of my channels such 
that the rereferenced dataset would be referenced against the new 
channel divided by 2?
resulting channel = old channel - (specific channel / 2)
By using 'reref' I wasnt able to do this..

How can I extract epochs by using conditional expressions such as: 
Extract all epochs after event-code x but only if event-code y is 
following within the next z ms?

Have you any ideas, why 'h' instead of 'EEG.history' doesnt work on my 
computer?

Thank you very much in advance!
Best regards,
Nils
