How to reconstruct head model for an EEG with double banana montage?

Hello BrainStorm experts,

I have an EEG file which is in Double Banana montage. Once I want to create a head model it gives me error due to the fact that the montages are not defined as a sensor. Also it wouldn’t let me to assign Generic electrode positions (19 electrodes). Is it possible that I can change this montage to single electrode recordings to be able to create head model?
Best Regards,

Hello
You would need to export again your recordings from your acquisition system as a monopolar montage (common reference) or in average reference. You won’t be able to process the data as is in Brainstorm (at least no in the way it is introduced in the online tutorials).
