[Paraview] [EXTERNAL] Assign colors to brain fibers

[Rafa x]

Yes, the id is available to color by after the 5 steps. However, the
mapColor showed is the last used in Paraview not the mapColor saved in
the previous process. For that reason I have supposed that mapColor
information is not saved in the vtk. Do you know some way to store the
mapColor in the vtk file to allow that other DTI programs can
interpret it?
