I don't have any example, but the idea is pretty simple. If you want to freeze
a point on the surface, open aseg.presurf.mgz and the surfaces for your
subject, eg,
tkmeditfv subject nu.mgz -seg aseg.presurf.mgz -surfs
Then edit the aseg.presurf.mgz to change the voxels where you want to freeze to
value 247 (FreezeSurface in $FREESURFER_HOME/FreeSurferColorLUT.txt)
Then run recon-all with -autorecon2-surfonly -autorecon3

External Email - Use Caution
So I never got a response for my question. At least can someone tell me the
recon-all flags needed after editing the aseg.presurf.mgz file. I am also
assuming that this feature is also available for 7.1.1.

I am curious about a feature introduced in FS 7.0 In the release notes it
says, "Ability to freeze the surface at points labeled 247 in the
aseg.presurf.mgz" I was interested to know what this feature can do. Do you
have any examples of when this should be used?
