Hi Alex,
you could try the topology correction, but we've never done it on a whole
brain, so I have no idea how it will go. The two hemispheres together
aren't going to be topologically spherical given the various commisures
that connect them. Maybe you are better off simply merging the two
topologicall correct surfaces at the end?
cheers,
Bruce

Hi
I would like to have a single white and pial surface for FEM based field
calculation in the brain. I got these surfaces by tesselating from filled.mgz
and ribbon.mgz by changing the values in the volume files. Unfortunately the
surfaces don't have the acquired quality I need. They show some topological
inaccuracies.
Is there a way to use the freesurfer tools for topology fixing from starting
with a single white matter surface?
Cheers Alex
