Dear Case;
Sir, I actually wanted to know what you replied :-)

we can use "starting" coordinates and charges from other docking
programe..it was confusing me that whether we can use starting
coordinates and charges from other programe or not and then do dynamics
and mm_pbsa calculations giving AMBER charges
