Re: [gmx-users] query about structural consistency

I really appreciate your thoughts. I know about the words like "exact" or "correct" does not stand in such scenario. I just needed an expert opinion regarding the quality assurance of the equilibrated structure. People often tend to ask question like how can you say that your model is properly equi

Hello Mark, I guess that's an endless question and will vary based on what kind of ions used in equilibration. So how do I made a decision that I got the correct equilibrated structure for my production run ? Is it pressure, density, temperature convergence or I'm missing something? On Tue, Ma

[gmx-users] query about structural consistency

Hi, I just have a basic query. I'm working with a protein-ligand system with a goal of performing Umbrella sampling in gromacs. So first, after I build the complex, I'm going for NVT and followed by NPT equilibration of 20ns each. After equilibration, is it mandatory that my equilibrated
