Hi Navid,

why don't you email me one and I'll see if I can figure it out Bruce On Wed, 23 May 2012, Navid Shiee wrote:

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

  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

        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,
