[Eeglablist] electrode mislocalization

[arno]

Dear Rodrigo,

my expectation is that the mislocalization for independent components 
will be similar to the mislocalization for EEG/ERP. The reason is that 
both contain a scalp map of potential (although unlike ERP/EEG source 
localization, a component scalp map does not change over time).
For sure, it would be good to show that on real data though.

Best,

Arno
