Sir,
I'm new to simulation. is there any papers or materials (book or website) to
learn about the forcefields and their limitations. All the advice I get from
people is to select a ff and membrane based on the previous works on that
protein or protein family. I know its too much to ask but, can you please
suggest some papers/materials on forcefields and selecting a membrane. I'm
sure it will be useful to many beginners like me.
You already have a good starting point - identify what others do. Precedent is
important. Then ask yourself, why are others doing what they are doing? To
answer that question requires quite a bit of reading. Several days spent
reading about different force fields will save you months of wasted time if you
blindly choose a poor one for your simulations. The primary literature for many
force fields goes back over the course of decades, which will give you an
appreciation for the underlying design, assumptions, and implementation of a
force field. More recent articles certainly exist that have challenged these
force fields under different conditions.
Websites and textbooks would be convenient, but I have never seen anything
comprehensive on this topic. Maybe someone else has and can suggest it. There
is, however, a vast amount of literature that tests different force fields.
Some names that come to mind include Bert de Groot and Robert Best, who I know
have published several very nice force field comparisons, in addition to the
publications of the labs from which the force fields originate. Expect to
occupy a lot of time reading before doing any simulations - it is time well spent.
