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)

I am Bharti, a M.Tech./Ph.D student at School of Computer & Systems Sciences, Jawaharlal Nehru University, New Delhi, India. My area of interest 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.
