Progressively Hiding Atoms in SAMSON: A Smoother Way to Focus Your Story

When creating visually engaging molecular animations, it’s often important to guide your audience’s attention in a deliberate way. Maybe you want to zoom into the active site of a protein or gradually hide peripheral atoms as you move through a…

Making Atoms Appear Step-by-Step in Your Molecular Animations

OneAngstrom

When creating molecular presentations, showing everything at once can lead to visual overload — especially for larger molecules. Sometimes all you want is to walk your audience through a part of a structure, one piece at a time. Whether you’re…

How to Quickly Select and Organize Light Sources in Your Molecular Scene

OneAngstrom

When building a molecular scene in SAMSON, lighting plays a key role in making sure that your visualizations are both scientifically clear and aesthetically compelling. But if your project involves multiple light nodes—think of directional lights, spotlights, or ambient light…

Choosing the Right Color Palette in Molecular Visualization

OneAngstrom

Color can be more than visual appeal when modeling molecules—it communicates information, separates regions, and reveals trends. But choosing a color palette that fits your goals can be difficult, especially when you want clarity across complex molecular assemblies. If you’re…

An Easier Way to Work with Residue Selections Across Views

OneAngstrom

When analyzing biomolecular structures, a common frustration is keeping selections consistent across different representations of your model. If you select a residue or chain in a 3D viewport, it can be tedious to track it back to its sequence position—or…

No GROMACS Install? No Problem.

OneAngstrom

Installing GROMACS for molecular modeling and simulation has traditionally been a technical barrier for many researchers and students. It often involves downloading source code, managing dependencies, ensuring compatibility with specific compilers, and sometimes taking deep dives into system-level settings. If…

Controlling Visibility and Selection in Molecular Models with NSL

OneAngstrom

Working with large molecular systems often means dealing with a lot of visual clutter. Whether you’re preparing illustrations for a paper or simply trying to understand a structure better, it’s common to want to hide some elements and highlight others.…

A More Precise Way to Select Node Groups in SAMSON

OneAngstrom

When you’re working with complex molecular systems in SAMSON, quickly finding and editing specific parts of your model can be challenging — especially when your structure involves large biomolecules, molecular assemblies, or nested node groups. Fortunately, SAMSON’s Node Specification Language…

Quickly Visualize Symmetric Protein Assemblies from PDB Files

OneAngstrom

If you’ve ever loaded a PDB file into your molecular modeling environment only to find a lone asymmetric unit floating in empty space, you’re not alone. Most PDB files describe just the minimal repeating unit of a biological assembly or…

Getting the Right Molecular Selection with Selection Filters in SAMSON

OneAngstrom

When working on complex molecular systems, the ability to quickly select relevant atoms, residues, or molecules is vital. Whether you’re visualizing a protein-ligand interaction, preparing a simulation, or analyzing channels through a membrane, making precise selections can save time and…
