[Eeglablist] Add data channel

[Arnaud Delorme]

Dear Bill,

adding a new empty data channel:

EEG.data(end+1,:) = 0;
EEG.nbchan = size(EEG.data,1);
if ~isempty(EEG.chanlocs)
	EEG.chanlocs(end+1).label = '';
end;
[ALLEEG EEG CURRENTSET] = eeg_store(ALLEEG, EEG, CURRENTSET);
eeglab redraw

Hope this helps,

Arno

I can append channel, but if I check data channel, it protests. If I do not check that box, it does not change the channels (from 72 to 73).  I could add the new calculated channel to EEG.data.73, but the number of channels is wrong.  I could change the nchan but there is probably more to adding a channel than that.  Is there some simple (or not so simple) way of adding a new data channel?
