Re: [AMBER] REMD: What can I do with much larger replicas than the number of processors

Dear all,

Appreciate for all your help! Many thanks!

My plan is to obtain more probable conformations of my protein.

I’m going to try all your recommendatory methods, like H-REMD, aMD and GAMD.

What’s more, I’m also trying Hybrid-REMD which is introduced in Amber manual, applying a hybrid solvent system referring to both explicit and implicit model.

Let’s see what I would gain.
