[Eeglablist] Error when loading channel locations

Dear Jessica,

If you have non-EEG channels (typically fiducials) they are not counted as
a number of channels. In this case, if you have 128 EEG + 3 fiducials, 131
is the chanloc length and size(EEG.data,1) == 128. Make them match
carefully and it should work. Let us know if it does not work.
