[Freesurfer] MNI average brain in Freesurfer space

2017-09-05 Thread Anna Kasdan
Hi everyone,

Is there a freesurfer file/file format for the *average* MNI brain (as
opposed to fsaverage which is just based on different subjects)? Or is
there a way to turn MNI coordinates into freesurfer space? Thanks so much!

[Freesurfer] mne_surf2bem error persists after editing file in freeview

2017-09-25 Thread Anna Kasdan
I am trying to create a high-resolution image to use with mne in
mne_analyze. I first ran mkheadsurf -subjid s and this did not result in
any errors.

I then ran mne_surf2bem --surf ../surf/lh.seghead --id 4 --check --fif
s-head.fif
and ran into an error about vertices for a few of my subjects.

input  file #   1 : ../surf/lh.seghead / id = 4 / sigma N/A

output file   : EVO07-head.fif


New quad file : nvert = 288077 nquad = 294014

Triangle and vertex normals and neighboring triangles...[done]

Vertex neighbors...Too many neighbors for vertex 92055.


I tried editing the seghead.mgz file in freeview, and filled in the voxels
that were missing at the neck. I then reran the mkheadusrf command
(mkheadusrf -subjid s --noseghead), still with no errors, but got the same
error as before again when I ran the mne_surf2bem command.

Suggestions? Many thanks!

Anna
