mri_binarize --i seghead.mgz --min 0.5 --surf lh.seghead --surf-smooth 10

Is it possible to use a different function? Can I use mri_vol2surf on the seghead.mgz file? Or do you think that mkheadsurf is the right one to be using?

Thanks!!

Can you load it in tksurfer or freeview?

Hi FreeSurfer users, 

I have used the "mkheadsurf" command to create a head surface for my subject. However when I try to use "read_surf" to read the "lh.seghead" file that is created, the magic number is not one that is recognised. 

Having read some previous posts/questions with similar problem/error, I think the problem is probably within the "lh.seghead" file. I think someone wrote that incompatibility of the magic number means that the surface is corrupted. Is there a way to check errors of mkheadsurf? Or whether something is wrong? It looked fine in freeview. 

Does anybody have any advice?

Thanks,

Maheen
