Why Molecular Labels Disappear When You Zoom Out (and How to Fix It)

Have you ever placed labels to annotate atoms, residues, or molecules in your SAMSON model, only to see them vanish as you zoom out? This can be frustrating, especially when preparing visuals or sharing interactive models. Fortunately, there’s a systematic…

Quickly Filter Visible Notes in SAMSON Using NSL

OneAngstrom

When working with complex molecular models in SAMSON, adding notes to nodes can be a convenient way to annotate and keep track of specific elements or structural features. However, as the number of notes increases—especially in collaborative or long-term projects—it…

Filtering Aromatic Atoms with NSL in SAMSON

OneAngstrom

When analyzing or designing molecular systems, selecting specific types of atoms quickly and precisely can save a lot of time and reduce errors. One of the frequent needs among molecular modelers is to isolate aromatic atoms across complex molecular structures.…

Installing Older Versions of SAMSON: A Quick Guide for Molecular Modelers

OneAngstrom

If you’re a molecular modeler working in a highly specific environment—whether you’re replicating previous results or using plugins that only support certain versions—it can be essential to install an older version of SAMSON. The good news? SAMSON provides a clear…

Get More Control Over Molecular Backbones with Attribute Filtering in SAMSON

OneAngstrom

When you’re modeling large biomolecules, it’s not uncommon to find yourself overwhelmed by the number of elements in your scene—atoms, residues, chains, backbones, materials, and more. Sometimes all you want is to quickly isolate certain backbone fragments, say, those with…

Save Time with Quick Groups in SAMSON

OneAngstrom

Working on complex molecular systems often means jumping back and forth between different parts of a structure—ligands, receptors, water molecules, or specific chains. Manually reselecting these parts again and again is time-consuming and can break your flow. That’s where Quick…

Your Molecular Timeline: Navigating History in SAMSON

OneAngstrom

In computational molecular modeling, trial and error is often part of the discovery process. Whether you’re building a structural model, setting up a simulation, or analyzing a complex interaction, it’s common to make adjustments—some of which you’d rather undo. But…

Solvating MARTINI Coarse-Grained Systems Without the Headaches

OneAngstrom

Preparing a coarse-grained system for molecular dynamics (MD) simulations can be surprisingly tricky — especially when it comes to solvation. When you’re using MARTINI v.3.0.0 force field models in SAMSON’s GROMACS Wizard, one of the most frustrating issues you might…

A Quick Way to Emphasize Molecular Events: Using the Flash Animation in SAMSON

OneAngstrom

Molecular modelers and educators often face the challenge of communicating dynamic processes effectively—like binding events, conformational changes, or molecule appearances during reactions. In molecular animation, when and how certain elements appear or disappear can make a big difference in how…

Visualizing Ligand Unbinding Routes with Pathlines in SAMSON

OneAngstrom

One of the common challenges in molecular modeling—especially when working with drug discovery or protein-ligand interaction—is understanding how a ligand moves as it unbinds from a protein. Visualizing this motion not only helps interpret simulation results but also improves communication…
