Dear list,  
I have the same problem that was discussed in this message:  
[https://mail.nmr.mgh.harvard](https://mail.nmr.mgh.harvard).  
edu/pipermail//mne\_analysis/2016-January/003059.html

When running mne\_surf2bem to create the head surface to check my  
coregistration, I am getting the error:  
Warning: Too many neighbors for vertex X for quite a large number of  
vertices.  
I have tried fixing the surface with freeview, but I don't seem to be able  
to find all problematic points.  
Is there a way to directly localize the vertex number in freeview?

Thank you,  
Sophie

hi Sophie,

for coreg purposes you can safely use the --force option to make the high  
resolution surface.
