Quickly Filter Visible Labels in Complex Models

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…

Switching Selections Fast When Modeling Molecules

OneAngstrom

When working with complex molecular systems, switching between different parts of a model—like a ligand, a protein pocket, or solvent shell—can quickly become tedious. Imagine selecting a group of atoms, navigating to another component, and then needing to go back…

From Conformations to Clearer Pathways: A Quick Optimization Strategy

OneAngstrom

When modeling molecular systems, capturing the transition between two known structures—say, a ligand binding or unbinding event—often involves generating intermediate conformations. Although these conformations may be linearly interpolated or derived using dedicated algorithms like the Ligand Path Finder, they rarely…
