[AMBER] Finding percentage occupancy of pi-pi interactions

Dear all,

I would like to know if there is some way to characterize the pi-pi
interactions between a ligand and DNA base using cpptraj. Basically I would
like to see the percentage occupancy of a particular pi-pi stacking
interaction. Kindly comment on the same.

Additional query: In connection with the above, how could we find the
stacking energy between the ligand and the nucleobase? I am aware of the QM
calculations, but can something similar to the LIE be used for the
calculation of the same?

Thank you in advance.

Regards,
Sruthi Sudhakar
