[Eeglablist] bipolar channels for eyes movement recording

Dear Olga,

Yes, this is possible. Simply remove the location information for these 
channels (in the channel editor -- menu Edit > Channel locations -- 
blank the "theta", "radius", ... fields for these channels). Eye 
channels will remain in the dataset but will not show in topographical 
plots.

Best,

Arno
