[Eeglablist] sources localization

[Arnaud Delorme]

Dear Maria,

you may ignore this message. This is just for expert users. EEGLAB by  
default considers the noze in the +X direction. When you read a file  
and you set the noze direction to a direction which is different from  
+X (in the channel editor interface), upon pressing OK, EEGLAB will  
rotate your full montage so that the noze is in the +X direction. The  
process should be totally transparent to you.

Best,

Arno
