Hi Kyung

the thickness values are stored as "curvature" file format that you can load into matlab with read_curv.m. Alternatively, you can convert them to ascii with mris_convert and do what you want with them. For each index, you can look up its location on the white or pial (or whatever surface). That is, for the 2nd thickness value (index 1), you would go find vertex #1 on the other surface and read its location that way

cheers

Hi Bruce, I am very new for FS, so did not understand you comments completely. sorry..

For cortical thickness from each vertex in one subject, which scripts should follow "mris_convert"?
And another question is how to recognize the location of each vertex in brain finally.

thank you so much

Kyung

      p.s. if you want the vertices to correspond, first run recon-all -qcache for each
      subject. That will generate a set of thickness maps in fsaverage space at predefined
      smoothing levels (so that the vertex numbers correspond across subjects)

                  Hi Kyung

                  you can load them into matlab or convert them to ascii if you want

                        Dear FS experts,
                        I could get QDEC image comparing two groups.
                        However, is there a way to get numerical values of cortical
            thickness in
                        each vertex?

                        Thank you

                        Best,
                        Kyung
