Hi! I’m a chemistry undergrad. For my research, I performed docking using Autodock Vina. For further validation, I tried docking using SwissDock too. But now, the two programs give different results. They predict different ligands to give the most favorable binding. I read that Autodock is more reliable. So, should…

It seems like most comp chemists lie on the spectrum in terms of their research application, which spreads from biochemical (proteins, drug design, biomolecular simulations, etc.) to inorganic materials (semiconductors, minerals/crystals, battery/electrolytes, alloys, metals, etc.).

SCIENCE By mattermodeling.stackexchange.com | 11 hours ago I’m not sure why you would use radius for gyration as a measure of solubility.

Which is more appropriate for the binding energy? Neither.

One of the main benefits of AWS is being able to select from over 400+ types of instances for running your high performance computing (HPC) applications. In addition to differences in number of cores, memory, and storage, AWS offers different architectures from Intel, AMD, and our own Arm-based Graviton instances….

namd-l: Re: CONVERT PSF to TOP grimaces I might be a little biased since I wrote TopoGromacs for my own needs, but I think it’s a fine way to generate the .top file GROMACS expects. This defines the system topology and parameters, which are combined with a .mdp file into…

We describe a step-by-step protocol for the computation of absolute dissociation free energy with GROMACS code and PLUMED library, which exploits a combination of advanced sampling techniques and nonequilibrium alchemical methodologies. The computational protocol has been automated through an open source Python middleware (HPC_Drug) which allows one to set up…

GROMACS molecular dynamics sim, development kit GROMACS is a versatile package to perform molecular dynamics, i.e. simulate the Newtonian equations of motion for systems with hundreds to millions of particles. It is primarily designed for biochemical molecules like proteins and lipids that have a lot of complicated bonded interactions, but…

About This Workshop GROMACS is a versatile software package to perform molecular dynamics, and is used to simulate different equations with hundreds to millions of particles.This Runbook will take you through the process of deploying GROMACS Software on Oracle Cloud. In this particular demo, we are going to achieve this…

POD-style object used by mdrun ranks to set and receive signals within and between simulations. Keep in mind that the values of signals are transmitted to other ranks through an MPI_Reduce after casting them to a real (so the signals can be sent together with other data). This means that…

Comparing the performance of real applications across different Amazon Elastic Compute Cloud (Amazon EC2) instance types is the best way we’ve found for finding optimal configurations for HPC applications here at AWS. Previously, we wrote about price-performance optimizations for GROMACS that showed how the GROMACS molecular dynamics simulation runs on single instances,…

Join the Research Computing Team on Zoom for a two-hour long workshop on molecular dynamics simulations Friday (Oct. 22) at 1 p.m. This workshop will cover the three MD engines currently available on WVU HPC resources: NAMD, AMBER and GROMACS.  This workshop is meant for beginners and intermediate users of…
