Dear prof. Bruce
Thanks once again. As you clarify that each brain has different number of
vertices. But still I want to ask the followings:
1) How to map these on some standard template say Freesurfer template and
then retrieve cortical thickness for each vertices?
2) How to identify the location of each retrieved cortical vertices?
Kindly guide me for the same. I'll be highly thankful to you.

yes, each brain has a different number, sufficient to get about 1mm
isotropic resolution. You can use our spherical averaging to map them to a
common coordinate system with the same # of vertices if you want (I think
mri_surf2surf will do this)
cheers

is pattern recognition and image processing. In one of my research work, i
used freely available freesurfer software to find cortical thickness using
recon-all -all command.
But, while retrieving cortcal thickness maps using read_curv() function, i
am getting different number of vertices for different brains. Are
different
number of cortical vertices possible for two different brains? I have gone
through FAQ provided by Freesurfer but i did not find any related answer.
Kindly clarify.
Thanks in advance.
