Yes Dr. Dallas, I have gone through free energy analysis tutorial, But I'm wondering that whether this tutorial is working for large molecule like protein or not? Because the tutorial has explained methane only. Your feedback will highly be appreciated. Thanks! Amir On Sun, Nov 19, 2017 at 5:54

Thanks Mark, Depends what you mean by "stability." Actually, I don't know the role of metal ion if it is used as co-factor by a particular protein. I thought to do comparative analysis by MD simulation which might predict the possible role of metal (in this case Zn^2+). Other analysis like RMSD, R

Hi, Depends what you mean by "stability." A well designed study could seek to measure or estimate the difference in the free-energy of folding, but that would probably require an infeasibly large amount of sampling, and be highly dependent on the quality of the parameterization of the metal-protei

Hi gromacs users, I want to calculate the energy for comparative analysis of protein with and without metal ion, wherein I would like to determine the influence of metal on protein structural stability. I have used gromacs for simulation. Please suggest me how to do this kind of analysis? Should i
