Some more information about the problem: vmtkcenterlines sometimes throw
out following warning during the process.
Generic Warning: In /projects/mice/xzhang/VTK/src/Common/vtkMath.cxx, Line
544
Unable to factor linear system
Warning: In /projects/mice/xzhang/VTK/src/VTK/Graphics/vtkDelaunay3D.cxx,
Line 487

Appreciate if anyone can suggest some solutions. Thanks.
