[Eeglablist] Must reference channel be removed prior to ICA?

Dear all,

Sorry for asking the same question again but I am confused because of opposing replies. One reply was that it is okay to keep Cz for ICA when Cz is the reference channel for importing Biosemi EEG data into EEGlab (the reference channel is flat after the data were imported). The other reply was that when Cz is the reference channel for data import it must be removed prior to ICA.

Could you please let me know which reply is the correct one?

Thank you very much in advance!
