Do I need ECG channel to run "artifact_ecg"

W/ a 041809 Fieldtrip, I tried to run the following lines but got some error (see
below). I don't have ECG channel in my data, that's why I use a left-most
MEG channel w/ apparent cardiac interferences instead. Any suggestion how
to fix the problem?
cfg = ;
cfg.trl = data.cfg.previous.trl;
cfg.dataset = data.cfg.previous.dataset;
cfg.continuous = 'yes' ;
cfg.artfctdef.ecg.channel = 'A229';
cfg.artfctdef.ecg.pretim = 0.25;
cfg.artfctdef.ecg.psttim = 0.5;
cfg.artfctdef.ecg.method = 'zvalue'; %peak-detection method
cfg.artfctdef.ecg.cutoff = 3; %peak-threshold
[cfg, artifact] = artifact_ecg(cfg);
current zvalue threshold = 3.000
keep the current value (y/n) ?
??? Undefined function or variable "labelmlt".
Error in ==> channelselection at 344
if findmlt, channel = [channel; labelmlt]; end
Error in ==> artifact_ecg at 238
sgn = channelselection(artfctdef.inspect, hdr.label);
