Thanks a lot, Justin. I do CG simulation using Martini force field. So maybe I can find some useful infomation on the forum of martini.

It is said that two groups are more accurate but when when i split them into two groups "Protein nonProtein", I found that fluctulation of temperature in group "Protein" are obvious, Im afraid that would have an effect on accuracy on my simulation results. So how many groups shall I use to control the temperature?
What protocol is used in published studies similar to what you're doing? Small
groups will have larger fluctuations in temperature, that's a given. I don't do
CG simulations, so I don't know how such groups are commonly treated.
