[Mne_analysis] MNI to vertex?

[Tom Holroyd (NIH/NIMH) [E]]

I'd use a kd-tree for this. If you have a list of vertices in b:

import numpy as np
from scipy.spatial import KDTree

b = np.zeros((nv, 3))
	... fill in b ...
k = KDTree(b)

Now, e.g., k.query_ball_point(b[j,:], 2.) will return a list of indices
for vertices within 2. units. You can query any (x,y,z) point and get
a list of nearby vertices.
