I want to make APBS calculation for protein-ligand(Calcium ion) in different environmental conditions(physiological and low IS conditions). For physiological condition, I am adding 150mM KCl salts; but for low ionic strenght condition, I want to only add the potassium ions to the system (based on my MD simulations parameters). I was wondering about the default settings for IS in APBs and the possibility of adding different amount of ions.
