The sensor specification (in your case the position of the EEG
electrodes, for other people the position of MEG sensors) is used for
spatial clustering. I suggest that you explicitely use the
neighbourselection function if you are interested in using
clustering. In the help of that function you can read how to specify
the sensor information.
However, since you write

it seems that you don't want to cluster. The default handling of the
configurations here is not optimal, since the default is to try and
make a neighbourhood structure (required for clustering) even if you
don't need it. I think that you can get around it with
cfg.neighbours = [];
I will change the function so that it handles the defaults better.
