[FieldTrip] Question about corticomuscular coherence tutorial

[Elizabeth Amadei]

Hi all,

I was working through the corticomuscular coherence tutorial, loading in the data and copying and pasting all of the commands into matlab, and I got an error message upon typing in the command fd = ft_connectivityanalysis(cfg, freq) to get the coherence. The message read:

??? Error using ==> ft_selectdata at 535
selection of or averaging across channels in the presence of both label and labelcmb is not possible

Error in ==> ft_connectivityanalysis at 157
  data = ft_selectdata(data, 'channel', unique(selchan));


Has anyone come across this error before and know how to resolve it?
Thank you for your help.
