hi,

I don't think we have an off the shelf function for this but I would look at:

https://martinos.org/mne/stable/generated/mne.SourceEstimate.html#mne.SourceEstimate.to_original_src
https://martinos.org/mne/stable/generated/mne.morph_source_spaces.html#mne.morph_source_spaces

Similar to morphing, but different because I want to identify a nearest vertex rather than morphing a source estimate. I'm imagining this will involve finding the 3d coordinates of the fsaverage vertex in the spherical registration, then finding the closest vertex to that point in the individual subject spherical registration.
