[Mne_analysis] Re-referencing EEG electrodes in MNE

[Alexandre Gramfort]

Hi Alan,

I am not aware of a way to do this in a generic manner with MNE/MNE-Python
but it should not be hard.

At what stage of the analysis would you apply the new reference? on
Raw or Evoked?

Maybe you can draft a python function to do this and we can see how to
merge this to mne-python?

best,
Alex
