[Mne_analysis] mne_surf2bem dense head problem

[Eric Larson]

Hey all,

I'm having trouble making the dense head used for coregistration for a
couple of my subjects. When I run:

mne_surf2bem --surf ../surf/lh.seghead --id 4 --check --fif
${SUBJECT}-head-dense.fif

I get the error:

New quad file : nvert = 207742 nquad = 207794
	Triangle and vertex normals and neighboring triangles...[done]
	Vertex neighbors...Too many neighbors for vertex 104979.

This "too many neighbors" error occurs with or without the "--check"
option, if it matters. Has anyone run into this before and/or know a
solution? I had run the command "mkheadsurf -subjid ${SUBJECT} -srcvol
T1.mgz" to get the surface that mne_surf2bem is complaining about, so
I'm going to look for an option in there that could fix it.
