[Eeglablist] About reference channel

[Arnaud Delorme]

Dear Yang,

it is better to include eye channels in the ICA decomposition if you 
have them. For plotting, you may have to remove them if you use a 
different reference for them (bipolar reference). If your ICA 
decomposition is not satisfactory, try pruning the data of artifacts 
(though you do not have to remove eye movements). One of the most 
important thing is to remove current drifts. If it still does not work, 
try removing the eye channels.

This question arises periodically on the list. We are working to put the 
archive of the list back on the Internet (we are struggling to remove 
email addresses of participants).

Best

Arno
