			A list of (one-based) indices to the EEG channels to be acquired. These EEG channels appear first in the final ordering, before AUX and trigger channels.

			===AuxChList===
			A list of indices (each in the range 1 through 8 inclusive) indicating which Auxiliary channels are to be acquired. Aux channels are postfixed immediately following the EEG channels.
