[Mne_analysis] How to create Lead Field matrix based on only an averaged response MEG file

[Alexandre Gramfort]

Hi Junpeng,

if you have no MRI what has been done recently by Christian
is to use fsaverage as default anatomy. There is some python
code to do this but it's still work in progress:

https://github.com/mne-tools/mne-python/pull/379

You'll need a good understanding of MNE to use it.
