[Eeglablist] sources localization

[Blefari Maria Laura]

Hi everyone,
    I would like to post this question. When I select the 
MNI coordinate I got this message from the command window 
in Matlab: ?EEG checkset note for expert users: Noze 
direction now set to default +X in EEG.chanlocs and 
EEG.dipfit?. Does it mean that the reference system will 
change? I mean the +X axis is directed from the center to 
the nasion, -X axis is directed from the center to the 
inion, +Y will localize the left hemisphere while ?Y the 
right hemisphere? I want to be sure that I am right when I 
run the pop_dipplot function and read the source 
localization coordinates.

Thanks in advance for any kind of help.
