Hi Bruce,
Thanks for the quick reply.
I really need the sphere representation of the surface.
When you say its harder, do you mean that mris_fix_topology wouldn't be able to automatically project it onto the unity sphere? I would need to make manual adjustments to fix handles and holes and then use mris_sphere to create the sphere surface?
Can you please send more information about where or how it has been done before?
Thanks in advance for any help, Leonardo

Hi Leonardo,
we don't generate such a surface by default although we have created them on occasion. There's no standard procedure for doing so. It would be easy to create one that isn't topologically correct (e.g. run mri_mc on the white matter of the aseg), but harder to create one that is. cheers Bruce

Hi,
I'm trying to save the white matter surface as a gifti file so I can use it outside the freesurfer to implement an EEG dipole fitting, but I'm not sure if this is the best way to do it. I searched old posts in the list, but didn't find an answer. The problem is how to export the whole cortex, and not only one hemisphere.
I'm using
mris_convert subjects/subj1/surf/lh.white ~/subj1.lh.white.gii mris_convert subjects/subj1/surf/rh.white ~/subj1.rh.white.gii
and trying to mix the two surfaces inside my program, but I guess it's not right, because the middle of the brain is opened. I have two closed surfaces, and I would like to have one close mesh, without creating new faces and ignoring vertices in the middle.
Sorry i this is confusing, but the question is: Can I export one closed surface of the whole brain with freesurfer?
Thanks in advance for any help... and Happy New Year!
