[Eeglablist] Channel Locations for BioSemi

[Vincent LeBlanc]

Hi Enzo!
If I keep the original labels, it can't find any coordinates. If I set the
labels to FP1, FP3 etc. instead of A1, A2, etc., I do get coordinates.
However, when I plot their location, some of the channels are off the head.
Is that simply an effect of not having a 3D map of their localisation?
