If you've already run qcache, then it will be in the subject/surf folder
with a name like lh.thickness.fsaverage.fwhm10.mgz

But, amount and location of vertex are different among subjects.
As far as i understand, it is the subject space, not common space. is that
right?
If so, how can i get the thickness values in common space to
Hi Kyung
you should look at the mris_convert help. It has an example of how to
convert a scalar overlay like a curv file to ascii:
Convert a scalar overlay file to ascii:
mris_convert -c lh.thickness lh.white lh.thickness.asc
it needs the surface as an input to do the conversion properly.
Hi Bruce
I found a directory having a file with ".curv", open terminal and run
following command.
[root@localhost surf]# mris_convert rh.curv rh.curv.asc
nquads=4587523, nvertices=476
ERROR: MRISread: file 'rh.curv' has many more faces than vertices!
Probably trying to use a scalar data file as a
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 surf
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
Kyun
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)

yes. You can use mris_convert to make an ascii file, or read_curv.m to
read them into matlab.

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
