Hi,

Thanks for your suggestion. When I tired to use mris_convert I got a bunch of "freadFloat: fread failed" errors. To make sure there is not an incompatibility from my vtk files, I used mris_convert to convert Freesurfer surfaces to vtk and then convert them back to .pial, but I still got the same error. Is there any other way that I can try?

Thanks,
-Navid

Hi Navid,

I think mris_convert will take a .vtk file as input. Try it and see if it works:

mris_convert lh.pial.vtk lh.pial
mris_convert lh.white.vtk lh.white

you can then use mris_thickness to calculate the thickness measures.


cheers
Bruce

Hi,

I have generated inner and pial surfaces using another method. However, I am
interested in computing the cortical thickness using the method implemented
in Freesurfer. My surfaces are in vtk format. I was wondering how I can do
this, if this is at all possible.

Thanks,
