Smarter Polymer Design with Custom Monomer Sequences

For molecular modelers working with synthetic or biological polymers, flexibility in defining and reusing molecular building blocks is critical. When creating complex polymers—especially those with repeating units or custom architectures—managing monomer sequences efficiently can save time and reduce errors. This…

Freeze and Refine: Minimizing Just a Part of a Molecule in SAMSON

OneAngstrom

When working with complex molecular systems, sometimes you only need to refine a small region of a structure — perhaps an active site, a flexible region, or a newly added side chain. Re-minimizing the entire molecule can be slow and…

Quickly Filter Visible Labels in Complex Models

OneAngstrom

When working with large molecular systems, it’s easy for the workspace to become visually cluttered. Especially when label nodes—used for annotating or identifying parts of a system—are scattered across complex models. Finding which labels are visible, filtering out those that…

Tracking Molecular Motion with Center-of-Mass Pathlines in SAMSON

OneAngstrom

Visualizing how molecules move over time is a recurring challenge in molecular modeling. Whether you’re studying ligand unbinding, domain shifts in proteins, or atom group trajectories, understanding motion is crucial. One particularly useful concept is the center of mass (COM)…

Tired of Format Frustration? Here's How Molecular Modelers Can Streamline File Imports

OneAngstrom

Whether you're a visualizing expert or just getting started in structural biology, you've likely faced this headache: You download or generate a molecular file—say a PDB or an electron density map—only to realize that your modeling platform can't open it.…

Filtering Molecular Backbones by Atom Count in SAMSON

OneAngstrom

When studying large molecular systems, zooming in on relevant structural groups is essential. Whether you’re analyzing protein backbones, coarse-grained models, or complex supramolecular assemblies, being able to filter groups of atoms based on structural attributes saves considerable time and helps…

How to Limit the Protein Docking Search Space in Hex

OneAngstrom

If you’ve ever performed protein-protein docking using tools like Hex, you’ve probably encountered this common challenge: docking takes time, especially when the search space is large and the receptor and ligand can explore orientations across the full 360° sphere. While…

A straightforward way to export ligand trajectories from SAMSON

OneAngstrom

If you’ve ever needed to extract the trajectory of a ligand along an unbinding path for further analysis, you’re not alone. For molecular modelers working on free energy calculations, reaction coordinate generation, or enhanced sampling setups, being able to export…

Why Understanding Node Types in SAMSON Can Save You Hours

OneAngstrom

If you’ve ever found yourself buried under a complex molecular system and unsure how to efficiently interact with its components in SAMSON, the answer might lie in understanding Node Types. Mastering node types is key to organizing, manipulating, and visualizing…

Filtering Structures by Atom Count in SAMSON’s NSL

OneAngstrom

When working with complex molecular assemblies, one of the key challenges for computational chemists and molecular modelers is filtering out irrelevant parts of a structure to focus only on regions of interest. You might be looking at thousands of components…
