One common obstacle faced by molecular modelers when working with molecular dynamics (MD) simulations is managing input files correctly between simulation stages. If you’ve ever had to rerun an NPT equilibration in GROMACS just because you didn’t set the right…

For molecular modelers analyzing protein conformational changes, it’s often not enough to just visualize start and end structures. Understanding the atomic-level movements along the transition path is key to gaining insights into protein mechanisms, identifying stable regions, and preparing for…

Researchers and developers working in molecular modeling often face a common challenge: how to integrate their own simulation methods, tools, or workflows into their modeling platform. Whether it’s a newly developed algorithm, a custom-built force field, or a connector to…

Understanding how a ligand navigates through a protein tunnel or binding pocket is crucial in molecular modeling. If you’re analyzing ligand unbinding or conformational transitions, it’s often difficult to see the bigger picture of a movement just by playing through…

When working on complex molecular systems, it often happens that you want to optimize only a specific part of a molecule—perhaps just a side chain, a functional group, or a distorted region—without disturbing the rest of the structure. This is…

When working with complex biomolecular systems, labels are powerful tools. Whether highlighting residues of interest, displaying atomic distances, or tracking a subset of molecules, well-placed labels bring clarity. But when zooming in and out of large systems, things can quickly…

In molecular modeling, creating compelling and instructive animations often means clearly highlighting key interactions or transformations—without distracting motion in other areas. Ever tried to animate a docking event only to find unrelated atoms drifting around, distorting the focus of your…

When preparing a biomolecular system for simulation in GROMACS, one often encounters the need to remove water molecules — typically those originating from crystal structures in the Protein Data Bank (PDB). In many cases, however, not all water molecules should…

Biological assemblies—like protein complexes or viral capsids—often exhibit beautiful symmetry, which can be more than just aesthetic. Understanding and using this symmetry is essential in many molecular modeling workflows: from reducing computational cost to designing symmetric mutations. That said, if…
