How to show particle postions in paraview?

Hi all,
I am trying to get the positions of particles in Paraview, I see the file of positions in each time step in OpenFOAM folders after the solution is done, but I dont see the position field in paraview, I tried foamToVTK and foamToEnsight, but both of them dont show the field positions in the lagrangian part.
thanks for your time
