Preview and Generate Protein Symmetry Mates Interactively

When working with proteins in PDB format, one of the recurring challenges is understanding how a structure fits into its larger biological context. Many deposition files contain only an asymmetric unit—just a fragment of the full biological assembly. This often…

Visualizing the SARS-CoV-2 Spike’s Opening in 3D: A Practical Guide for Molecular Modelers

OneAngstrom

Understanding molecular motion is crucial in structural biology and molecular design, especially when studying protein-ligand interactions or conformational transitions. But modeling flexible structures like the SARS-CoV-2 spike protein can be technically challenging and time-consuming. Knowing how to simulate such motions…

Quickly Filter Visible Labels in Molecular Models Using SAMSON

OneAngstrom

When working with complex molecular systems in SAMSON, label nodes play a key role in annotating structures, highlighting specific data, and guiding collaborators. However, once your scene becomes crowded, it can be hard to keep track of which labels are…

Stop Wasting Clicks: Filter Render Presets in SAMSON with a Few Keystrokes

OneAngstrom

A common pain for molecular modelers and visualizers is efficiently managing complex scenes with many render presets. When dealing with multiple visual styles—cartoon, licorice, surface, and more—it’s easy to lose track of your custom presets, especially in large systems. You…

Need to track how atoms move? Here’s a way to record their path during animations.

OneAngstrom

When preparing molecular presentations or designing animations of molecular mechanisms, one recurring challenge for modelers is tracking how atoms move over time. Whether you’re simulating a docking event, assembling a complex, or simply visualizing structural changes, keeping a clear record…

Visualizing Molecular Motions Without Running Full Simulations

OneAngstrom

Computing conformational changes in large macromolecular systems is often time-consuming and computationally intensive. What if you need a representative trajectory between two known structures but can’t afford to run costly molecular dynamics simulations? For molecular modelers looking to visualize and…

A Clearer View: Exploring Structures with Progressive Clipping in SAMSON

OneAngstrom

When molecular models get large and detailed, navigating and inspecting them in 3D can become visually overwhelming. Cluttered regions, overlapping atoms, or nested structures can make it hard to focus on specific internal areas of interest — especially in dense…

Exporting Ligand Trajectories from Path Simulations Without the Clutter

OneAngstrom

When studying ligand exit pathways, molecular modelers often need a clean export of just the part of the system that matters: the ligand moving along its path. Exporting the full atom trajectories of an entire protein-ligand complex can quickly create…

Quickly Identify and Organize Labels in Your Molecular Models

OneAngstrom

When working on complex molecular models, clarity is everything. Labels—whether for atoms, residues, or regions of interest—help molecular modelers keep track of critical information. But as models grow in size and complexity, managing these labels efficiently becomes crucial. That’s where…

Still Using the Wrong GROMACS Version?

OneAngstrom

If you’re working with GROMACS for molecular dynamics simulations, there’s a good chance you’ve encountered compatibility issues between versions. Whether you’re trying to reproduce published results, align with your lab’s computing environment, or troubleshoot strange errors, using a specific version…
