Hi Martin,

yes there was no individual pp_surf.vtk and pp_para.vtk surfaces, although there is a pp_surf_para.vtk surface. When I tried to view them (pp_surfSPHARM) in 3d slicer, the viewing window looks funny (images covers the entire viewing window like a giant curtain), despite the fact that the original gipl volume looks normal.

Regards
Yann
