I see. Sorry I don't know the details of the vtk surface file format.
Maybe Ruopeng does? Does it store ras2vox info?

Yes, when I import the original file (lh.pial) and the converted .vtk file
(lh.pial.vtk) in
Freeview, there is a mismatch.
I am using the vtk pial file in a C++ application to visualize the brain. Now I
want to import the
CT NIFTI into
this application to extract the iso-surface using a marching cubes algorithm.
In order to avoid
transformation
matrices etc. it would be great to process the CT NIFTI in such a way that it
matchs the converted
vtk files.
Thanks for your help.

How do you know it is shifted? Do you visualize it in freeview? And what
are you intending to do with the CT? Maybe you are better off sampling it
onto the surface than trying to map the surface onto the CT?
