[Mne_analysis] Identifying adjacent sources

[Gladia Hotan]

Hi Alex,

I'm still not sure how to get the adjacency matrix, based on the example.
It seems like lh_faces and rh_faces contain the faces from the original
cortical parcellation, before some sources are removed? I have an ico 3
source space. My leadfield matrix has 1162 sources in total. Thus
fwd['src'][0]['vertno'].shape = 581 and fwd['src'][1]['vertno'].shape =
581. However, fwd['src'][0]['usetris'].shape = 1280 and
fwd['src'][1]['usetris'].shape = 1280, so I'm not sure which faces
correspond to which vertices?

Thanks and Best,
Gladia
