[gmx-users] a residue move in extremely large scale in MD

[Acoot Brett]

Dear Albert,


I hope I can support my MD results with some bioinformatics data. For example, it indicates the highly movavle residue I mentioned in my previous e-mail is not conserved at all, and it is only specific that structure.

For your 10X with different seed simulation, does it mean the production time scale changes to 100 ns, or does it mean I run 10 rounds of 10 ns MD to vierify the results? For GROMACS, the seed is choosen automatically, do we have the method to choose it manually?

For the converge you mentioned, I agree for some simulations 10 ns is not enough, but I think within 10 ns if what you want to determine has converged, that would be fine. For converge, which parameters do you use to decide whether it has converged?
 
There are some Journals accept computational biology research results without the support of biochemistry data, can you suggest these Journals to me?

I am looking forward to getting your reply.

Cheers,

Acoot

you have to submit 10X with different seed simulation to confirm your results. 10ns is not converged for some simulation, you should also extend it in nowadays timescale level.
Moreover, if you don't have biochemistry data to support your idea, nobody will believe your results.

good luck
Albert
