[Mne_analysis] Inquiry regarding MNE-Python

[Eric Larson]

        External Email - Use Caution        

Is it possible your electrode locations are in millimeters instead of
meters? MNE-Python expects all locations to be in meters. One way to change
this would be to use raw.get_montage(), change the channel positions,
create a new montage with make_dig_montage, then call raw.set_montage using
the modified one.
