what version of FS do you have? You can try runing it with -pial pial but I wouldn't think that is needed. Is the lh.pial in /misc/data41/yuex/recon_test/test_DB48/surf/

and is it readable?

Yes, lh.pial exists

it only looks for that if it can't find lh.pial. Does that exist?

Hi Bruce,
the mris_thickness was looking for ?h.gray file to run correctly.  But no
such file exists.  The freesurfer used is 5.3.  Any ideas?
The command line is: mris_thickness test_DB48 lh lh.thickness
The error: reading gray matter surface
/misc/data41/yuex/recon_test/test_DB48/surf/lh.gray

 MRISread(/misc/data41/yuex/recon_test/test_DB48/surf/lh.gray): could not
open file.
Thanks,
Xiaomin

it creates a file in curvature format, yes. Did you try mris_fill for the
wm.mgz? It won't be exactly the same as the one we would generate. You
could use mris_fill to generate the interior of the ?h.white surface,
then use the aseg to remove non-wm voxels I guess

Thanks very much.  Does this create curvature file?  Again, is it possible
to generate wm.mgz from those files?

I think just the ?h.white and ?h.pial

     Hi Bruce,

     Thanks for your response.  What's the inputs to the
     mris_thickness?  I need the wm.mgz to generate the ratio of gray
     vs. white matter.

the thickness you can generate using mris_thikness. Why do you want to
generate a wm.mgz? I guess you could from the wmparc

Hi All,

Cortical surface reconstructed using caret from a high resolution MRI
data
(0.25 mm) has been converted to freesurfer format, and viewed correctly
using freeview.  My questions are whether it is possible to generate 1)
a
?h.thickness from the ?h.pial and ?h.white; 2) wm.mgz file using
?h.pial a
nd
?h.white

Thanks very much for your inputs.
Xiaomin
