Designing molecules is one of the central tasks in molecular modeling. But when it comes to building or editing small molecules—especially during early-stage design or cleaning up structures—many scientists still rely on separate 2D sketching tools, later importing their work…

One challenge that many molecular modelers face with molecular dynamics (MD) simulations is ensuring continuity and consistency between equilibration and production runs. It may sound trivial, but mistakes in setup parameters—particularly when switching from NPT or NVT equilibrations to production—can…

Designing polymers with custom sequences can be repetitive and tedious, especially when you’re experimenting with variations of monomer units. If you’ve ever found yourself manually repeating patterns or trying to track down bond types between units, there’s a more efficient…

When preparing scientific presentations or molecular animations, one common frustration faced by structural biologists and molecular modelers is presenting complex atomic transformations in a clear, smooth, and repeatable way. Often, the motion of molecules is illustrated frame-by-frame, requiring tedious positional…

Adding custom index groups is one of those things that always sounds more complicated than it needs to be. For many GROMACS users, especially those analyzing complex molecular systems or planning umbrella sampling simulations, grouping atoms efficiently is a routine…

When preparing a molecular system for simulation, it’s tempting to jump straight into running molecular dynamics. But, as every experienced modeler learns, skipping the pre-processing step can lead to frustrating errors or even incorrect results. If you’re using SAMSON with…

When working with complex molecular models, it’s easy to get pulled in many directions—building structures, editing geometries, running analyses, visualizing data. With so many tools available in SAMSON, some users wonder why the platform restricts them to using only one…

Molecular animations are a powerful way to explain complex ideas—especially when presenting dynamic molecular processes such as docking, conformational changes, or molecular interactions. However, many researchers and educators struggle with getting things to appear exactly when they want during a…

When modeling molecular systems, capturing the transition between two stable states can be crucial—whether you’re studying ligand unbinding, protein conformational changes, or reactions at the atomic level. Molecular modelers often face the challenge of refining the rough paths generated from…
