Dear FreeSurfer experts:
I am confused how vertex positi=
on is determined. Is the vertex's position on surface is determined? An=
d is the distance between each two vertex the same=EF=BC=9F
Bests=EF=
=BC=8C

Each vertex in fsaverage is mapped back to the surfaces of 40 subjects.
The xyz for the vertex is the mean of the mni305 coordinates across all
subjects.
> And is the distance between each two vertex the same？
No, depends on the subjects in the average
