Hi all, I have a similar problem using Paraview: When I visualize the surface lh.pial and the anatomical image brainmask.mgz using FreeView they nicely overlap; however, after I convert lh.pial to lh.pial.vtk and brainmask*.mgz* to brainmask*.mha* and visualize them using Paraview, they are in

tksurfer always uses the ?h.orig coordinates. Also keep in mind that the vertex index is 0-based whereas matlab is 1-based. When you click on a point, you should see something like the following print out selected vertex 123491 out of 163842 current -39.11 15.65 11.26 orig -55.67 -10.37

Dear Experts, I tried to extract vertex coordinates information from 'fsaverage/surf/lh.pial' file using matlab function 'read_surf', but I found that the coordinates returned by the function are different from what I saw in tksurfer, here are the screenshots: The vertex index starts from 0 in
