[Mne_analysis] MNI to vertex?

Hi Alex,
I did, but I'm looking at sources not contained in the surface source space
(i.e., cerebellum). All I really want to do is extract the raw source
timecourse for a given set of MNI coordinates, for use in time frequency
analysis, coherence, etc. I suppose it would be possible to go through the
file with lcmv_raw and drop the vertices of no interest (≈99%) from each
time sample prior to saving, but that would be kind of a kludge.
For now it's just a handful of subjects, I can always do it in Graph with
an SSP as my spatial filter.
Thanks
Jon
