[Eeglablist] Comparison of EEG components to depth recordings

[Ramesh Srinivasan]

Hi David

Your reviewer is not wrong. Your ica component will contain some noise from
(for example emg) that is subtle.

Btw it's also likely that if you labeled some ica components as artifact
some data was lost there too.
