[Biopython] clustering pdb

[Bala subramanian]

Friends,
I have around 3000 pdb files obtained from MD simulations. I would like to
know if it is possible to cluster the pdb files using any of the biopython's
bio.PDB or other modules. If so, i would appreciate if you could provide me
a sample code.

Is there any utility in Biopython to handle MD trajectories obtained from
common packages like gromacs, amber etc ?

Thank you,
Bala
