[Eeglablist] Re-referrence to average and add Cz back

[Makoto Miyakoshi]

Dear Fang-Yu,

> If I would like to add Cz back with computing average, should I operate "
're-reference'-> 'Compute average reference' with 'add current reference
channel back to the data' ?"

Compute average reference first and then interpolate Cz next.

> I would like to ask more question. You mentioned one(any) channel need to
be discarded after computing average. How do I discard one channel? I
operated " 'Edit' -> 'Channel locations' -> 'delete channel' " by EEGLAB,
but it didn't work. I'm not sure it is right to operate like this.

Yes this is confusing. Sorry for that. What you need to do is to 'Select
data' and not channel editing. Select a channel to discard from the list,
check the box to perform rejection for the selected (otherwise it'll leave
the selected).
