Hello! 
I need to calculate the free energy of complex formation between protein A and 
ligand B. I am about to simulate in solution the molecular dynamics of A, B and 
AB complex separately and calculate the free energy of each system using g_lie. 
Then, I suppose, deltaG = G(AB) - (G(A) + G(B)). 
Is it a correct algorithm? Or maybe it's better to use "slow-growth" method 
(whith lambda = 1 for the absence of ligand in the binding pocket) to calculate 
the difference between G(AB) and G(A)?
Thank you!
