Matt, Thank you very much for the clarification. None of my calculations have involved combined insertion/deletion. I have always picked the state that has more atoms for my starting state, then mutated toward the state with fewer atoms. This means that I don't have to re-do recent simulations

Sorry about all of the confusion. Basically, the answer to this depends on what exactly you're doing. (I should really write all of this up in a tutorial soon). The way I think about it is that there are two fundamental principles you need to keep in mind, and you can do it any way you can cook

Matt, After previous discussions that suggested separating vdw and charge mutations, I thought it was literally a 2 stage process. In one stage I modify all charges (including those for disappearing atoms going to zero) from their starting values to their final values, using 10 lambda points
