External Email - Use Caution
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?
