[Eeglablist] Error with Creating Channel Locations

[Brittany Alperin]

Hi Suraj

For your reference (Nz), try unchecking the "channel in data array" box. I
think that lets eeglab know that that's your reference channel. Maybe
someone else could help with the nuance as to why that's the case, but I'm
pretty certain that will solve your problem.
