Dear Lorenzo,
I was also thinking of scaling the charges of atoms of interest, but I
would rather prefer to scale the interactions itself.
I am doing the explicit water simulations so changing the dielectric
constant is not possible, unless I'm mistaken?
In addition, I am simulating a large system (enzyme+water) and I just
want to scale interactions between few pairs of atoms, and treat other
interactions in usual way.
Best,
Antonija
