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.

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,

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,
