Hi Paul

here is a generic pipeline (from BIDS import and preprocessing to stats) 
we wrote with Arno:

CRD - ICA - IClabel - that's it, data ready :-)

If this is the case, we can compare the chanlocs structure before and after clean raw data. `rmChanIdx` stands for removed channel indices. You can access the channel labels with `EEG.chanlocs(rmChanIdx).labels` to see the labels of the removed channels.
