[ITK-users] (Tarjan's) filter to detect/mark nodes belonging to cycles in a (un)directed graph

[Dr. Roman Grothausmann]

Found what I needed when searching for connectedcomponents (not loops, cycles or 
tarjan...)
vtkBoostConnectedComponents or even also vtkPBGLConnectedComponents does the trick
NB: "Find Data" of paraview does not work on the results because the array names 
contain spaces, removing those and all works.
