Hi Qizhu,
1. These files do not directly contain geometry information, but there are other files that do (eg, lh.white). You can use the mri_surf2vol program to convert them into a standard volume file like nifti. 2. You can use mris_convert to convert to ascii. The values are listed in the vertex index order. 3. Don't know

Dear experts,
I am greenhand for using FS, and am looking for ways to use the FS generated parameteric files, such as *thickness.mgh, *sulc.mgh, etc, outside FS. I got the following questions:
- Whether these files contain coordinate information for each
vertex, so I can transform them into image style file? If they do, that'll be very helpful. 2. If these files could not be tranformed into images, I am going to tranform them into ascii files using FS commands. The questions is: what's the orgnization of the output ascii file? i.e., from where to where inside the file is the header information, and does each line in the file stand for the value of a single vertex? How can I make such a ascii file which contains only vertex values in the right order? 3. I have obtained ascii files of individual's cortical thickness using mri_convert (with header inside), however, when I open it using different tools, the values look different, why?
Best wishes
