Dear Sir,

I did 10 ns dynamics of the complex and one water came
 between ligand and dna during equillibration and
stays there during full production.

That is why i want to calculate the binding free
energy in the presence of water molecule.

Is it possible to calcule binding free energy in the
presence of water. If possible please give some idea
about procedure.
