[Mne_analysis] Virtual electrode/sensor

[Alexandre Gramfort]

hi Karin,

what you call "virtual electrode" is what people commonly refer to as
a beamforming method. We have LCMV and DICS implemented in MNE-Python.
See our examples and documentation on beamforming.
As a side note, I find the term virtual electrode a bit misleading as you
still
need to solve an inverse problem. To me it's just a linear inverse method
among many variants.
