how can I view the EEG data of the AUX electrode in the MuseLab (EEG(4))? I manufactured the AUX electrode. The problem is if I want to view the EEG data(0…4) in the MuseLab, I have no signal at the AUX electrode (=flat). Do I have to activate the AUX input first, like in the app? Or is it enough if I check the box in the MuseLab?
Thank you very much for your help.
