[Mne_analysis] MNI to vertex?

how did you generate the source space with the cerebellum?

I am afraid there is no simple solution to your problem. You'll need to
hack something and ideally share your progress so it can benefit to
others. The clean solution would be to write a grow_label function
that would work with a volume source space ... there is a bit of work...

not as nice but if it works...
