[Freesurfer] A question about thickness computation for surfaces not generated by Freesurfer

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, -- Navid Shiee __

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 On Tue, 22 May 2012, Navid Shiee wrote: > Hi, >

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 sa

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 fro
