Thanks for the reply.

Sorry for the typing mistakes in my first mail. I meant to write "Is there
any problem". And by problem I mean consistency issues like having correct
born radii assigned to every atom etc.

How can I look and compare the born radii?

And for igb=5, Used "set default PBradii mbondi2" in tleap.

I want to calculate mm-gbsa free energy of binding of my ligand (which has
been parameterized) by running simulation in implicit solvent.

Sincerely,
