One of the common challenges faced by molecular modelers when performing Potential of Mean Force (PMF) calculations is preparing the input folder structure for the Weighted Histogram Analysis Method (WHAM). If you’ve tried setting everything up manually, you might have…

For many molecular modelers using GROMACS, editing .mdp (molecular dynamics parameter) files manually has long been the norm. It’s effective but error-prone, especially when experimenting with different simulation setups like energy minimization, equilibration (NVT, NPT), or production runs. Copy-pasting parameters,…

When working with molecular structures derived from NMR data, it’s common to run into geometry issues — atoms slightly out of place, bond lengths that don’t look quite right, and overall structural elements that need relaxation. Cleaning up these initial…

If you’ve ever tried to present complex molecular systems and felt limited by flat, static perspectives, you’re not alone. One common challenge in visualizing molecular models is finding ways to create depth and a natural sense of movement—especially in a…

When designing molecular presentations, clarity often hinges on what you choose to show—and just as importantly, what you choose to hide. The Conceal atoms animation in SAMSON offers a simple way to make atoms—and the bonds between them—disappear progressively. This…

If you run molecular dynamics simulations, you already know that properly equilibrating your system is critical—but easy to overlook or shortcut. A common frustration among molecular modelers is seeing their simulations fail or provide unusable data because NVT equilibration was…

If you’re working in molecular modeling, you’re likely juggling various file formats—PDBs from protein databases, XYZs from quantum chemistry, CIFs from crystallography, and many more. Each software tends to have its own preferred formats, making compatibility an ongoing concern, especially…

If you’ve ever spent hours perfecting a molecular animation or presentation in SAMSON, then you know how important it is to be able to share your work with your colleagues, your class, or your audience. But what’s the easiest way…

Creating clear and informative molecular visualizations can quickly become time-consuming—especially when dealing with complex systems like protein-ligand complexes, membrane assemblies, or large macromolecular structures. If you’ve ever found yourself spending more time setting up your visual representations than analyzing your…

When you’re creating molecular animations, there are moments when simply making an atom vanish instantly feels abrupt or visually jarring. Whether you’re teaching, presenting, or designing a publication-ready visual, gradual transitions can significantly improve clarity and storytelling. One frequently encountered…
