Average Reference for Source Stimation

[Francois]

Brainstorm forces your recordings to an average reference before source estimation, you don't have to do it explicitly.
For details, refer to this thread:

Reference of the gain matrix - EEG OPENMEEG BEM in Brainstorm

Hi Rasheeda, The models in Brainstorm convert all the EEG/ECOG/sEEG recordings to an average reference, you don’t need to do it explicitly. If you do want to apply an average reference montage to your recordings, use the process “Standardize > Apply montage”. To learn how to use the new montage interface, please read the EEG/Epilepsy tutorial. For questions on OpenMEEG, please contact the OpenMEEG developers: http://openmeeg.github.io/ Cheers, Francois
