For researchers in molecular simulation, computing Potential of Mean Force (PMF) profiles can be an involved task—especially when dealing with data from multiple umbrella sampling simulations. Manual WHAM (Weighted Histogram Analysis Method) workflows in GROMACS often require scripting, data formatting,…

When you’re building molecular models, clarity is everything. Whether you’re preparing a presentation, creating an educational resource, or documenting complex systems, annotations and visual cues can make your work much more effective. One underused but essential feature in SAMSON is…

Analyzing protein–ligand interactions is a key step in molecular modeling and drug design. Whether you’re a student, researcher, or experienced computational chemist, you’ve probably found yourself trying to figure out a fast and visual way to confirm whether your ligand…

In molecular modeling, attention to detail is everything. Whether you’re preparing a presentation, illustrating a mechanism, or crafting an educational video, highlighting specific structures—while letting others momentarily disappear—can improve clarity and focus. However, manually fading parts of a structure in…

Preparing a molecular system for simulation often involves tedious geometry optimization. Many modelers still use steepest descent by default, even though it’s not always the most time-efficient approach, especially with larger systems or flexible molecules. If you’ve ever waited too…

Running molecular dynamics (MD) simulations may sound routine, but if you’ve ever seen unstable temperatures, crashing systems, or hours of lost compute time, you know how crucial getting equilibration right is. One often overlooked challenge is setting up the NVT…

For many molecular modelers, managing simulation workflows can become complex when switching between tools, environments, and machines. If you’re using GROMACS for molecular dynamics, you probably know the challenges involved with setting up simulations locally: installation and compilation, environment configuration,…

When working with complex molecular models and simulations, keeping everything organized is not a luxury—it’s a necessity. Whether you’re comparing different ligands, running multiple simulations, or collaborating with others, your data needs to be structured and accessible. This becomes trickier…

When preparing molecular presentations for collaborators, conferences, or students, one common challenge is how to make complex models appear naturally and clearly during animations. Too often, researchers resort to tweaking transparency or manually toggling visibility, which feels clunky and disrupts…
