I think Bruce or Douglas can explain better.
However, the reason for both hemispheres being separated is that you need to mantain an S2 topological space.

Hi,
I would like to have a single surf file that composed of both right and left pial surf. Is there a way to do it in freesurfer?

can you tell us why you want such a thing? I have generated them before, but mostly for special-purpose applications. It's not something we routinely do On Fri, 20 Mar 2009 ppj@netfilter.com.br wrote:

Hi Bruce,
I am trying to create a volume conductor of human brain for FEM based source reconstruction. A nice surface of full pial (and other compartments like WM) layer is supposed to generate 3D FEM mesh by means of a meshing tool.
Cheers, Seok

I see. Sorry, we don't have any easy-to-use tools for creating a single pial surface. You could change the value in the filled.mgz so that lh and rh are the same and try tesselating/deforming it. I've done this in the past, but you have to mess around a bit to get it to work.
cheers, Bruce

you can get something like what you want with
cd $SUBJECTS_DIR/subject mri_binarize --i mri/ribbon.mgz --min .0001 --o mri/tmp.mgh mri_tessellate mri/tmp.mgh 1 surf/lh.both mris_smooth -nw surf/lh.both surf/lh.smboth tksurfer subject lh smboth
Note that eventhough you call it "lh" it has both hemis. "lh" is just to fool freesurfer into thinking it is a hemi.

Hi Seok-
Is there a compelling reason to combine the two hemispheres? Are you trying to identify similar vertices in both hemispheres?
