Hi Ali,
the thickness maps are stored in the file ?h.thickness, which is stored in "curvature" format for annoying historical reasons. You should be able to read the in matlab using read_curv.m and write_curv.m, or just load them in tksurfer for visualization purposes. We also have tools for comparing thickness across groups or correlating with other measures.
cheers, Bruce

Hello,
I am Ali Al-Radaideh from the University of Nottingham. I used freesurfer
on one set of my MRI data ( MP-RAGE 1mm isotropic resolution) and finished the recon-all step. I was able to display the thickness map but unfortunately I could not be able to find any file that gives me a quantitative measure of cortical thickness, as my intention is to measure the cortical thickness using freesurfer. Would it be possible to advice me on that, please?
Best regards
