When preparing molecular systems for simulation, removing water molecules is a common step. However, not all waters are useless. Some are tightly bound or located in active sites and play critical roles in structure and function. Deleting all crystal waters…

For many molecular modelers working in university labs, research facilities, or strict IT environments, installing new software can become a frustrating experience. Why? Because installing software often requires administrative privileges, meaning researchers have to wait for IT approval or assistance—a…

Running molecular dynamics (MD) simulations for a variety of protein systems often comes with a familiar headache: reproducibility and consistency across runs. 🧠 Whether you’re screening mutations, comparing homologs, or simply evaluating binding dynamics across different proteins, ensuring that all…

One of the recurring confusions among molecular modelers using GROMACS is selecting the proper input files for a production molecular dynamics (MD) simulation. This seemingly simple step can quickly become a bottleneck—especially when switching between equilibration and production phases, or…

When working with molecular simulations, seeing is understanding. But if you’re analyzing ligand unbinding events, conformational changes, or diffusion mechanisms, it can be surprisingly hard to visualize how a group of atoms actually moves through space over time. Often, researchers…

When working with molecular systems in GROMACS, energy minimization is a critical step to eliminate steric clashes and create a geometry that’s suitable for molecular dynamics. But how can you be sure it’s actually done properly? If you’ve ever launched…

If you’ve ever performed Potential of Mean Force (PMF) calculations using GROMACS, you probably remember the long list of scripts and careful file organization required to properly apply the Weighted Histogram Analysis Method (WHAM). Piecing together dozens of outputs from…
