Hello Mary Varughese,
So far as I understood, you want to take the ligand position with
respect to the DNA (as well as the ligand conformation itself) into
consideration.
I think the easiest way to do this is to do a RMSD calculation with the
DNA backbone mask first. This will align the structures. As a second
step (within the same praj/cpptraj call) you can use the cluster command
with the mask of the ligand and the 'nofit' flag.
with kind regards,
Achim Sandmann
