[Eeglablist] ICA Difficulties from Imported Biopac Data

[Ken Bennett]

Makoto,

Thank you for your response. Yes, I meant that I don't see any channels for
the ear lobes. I wasn't sure what I should then reference to in eeglab. I
will try re-referencing to the average. I just found some information about
doing this through the GUI, but do you know if there a script for doing
this instead? Any information would be greatly appreciated.

Thanks,
Ken
