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.
cheers

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 surface!
No such file or directory
what is wrong?
Thanks as always.

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

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
