Making Sense of Bond Types in SAMSON’s Node Specification Language (NSL)

When working with complex molecular systems, identifying specific bond types quickly can save researchers a tremendous amount of time. Whether you are filtering for hydrogen bonds, distinguishing between aromatic or single bonds, or building precise molecular queries, defining correct bond…

Trouble stitching together WHAM results? Here’s a simpler way with GROMACS Wizard

OneAngstrom

One of the recurring challenges molecular modelers face is extracting meaningful free energy profiles from umbrella sampling simulations. The workflow becomes particularly cumbersome at the post-processing stage — especially when dealing with tens or hundreds of windows, each producing individual…

From FASTA to 3D: Using AlphaFold-2 in SAMSON Without the Hassle

OneAngstrom

For many molecular modelers, an all-too-common bottleneck is transforming a protein sequence into a reliable 3D structure. Whether you’re designing a new protein or studying the function of an uncharacterized one, waiting on complex installations or manually preparing jobs can…

Making Molecular Models More Readable with Ambient Occlusion

OneAngstrom

One of the first challenges molecular modelers face when visualizing large and complex structures is how to make spatial relationships clear. Proteins overlap, structures twist around each other, and it’s easy to lose depth perception. A flat-looking model might look…

Animating Molecular Transitions with the Pulse Effect in SAMSON

OneAngstrom

Creating clear molecular presentations often means finding the right balance between visual aesthetics and conveying scientific meaning. One common challenge many molecular modelers face is how to highlight specific structures or changes without overwhelming the viewer. Whether you’re preparing an…

Visualizing the Opening Motion of the SARS-CoV-2 Spike Protein

OneAngstrom

For molecular modelers investigating viral infection mechanisms or working on therapeutic design, understanding protein conformational transitions is a frequent and sometimes challenging task. Particularly in virology, capturing how viral proteins change shape to interact with host receptors can help drive…

Take Just What You Need: Exporting Ligand Trajectories from Molecular Paths

OneAngstrom

Molecular modeling often involves watching how a ligand binds to or unbinds from a protein. But extracting only relevant atomic coordinates for simulations like free energy calculations can be tedious — especially if your tool exports everything indiscriminately. What if…

Exploring UFF Parameters: Small Tweaks, Big Impact

OneAngstrom

When performing molecular mechanics simulations, using force fields like the Universal Force Field (UFF) is a standard and powerful approach. However, researchers often find themselves frustrated when their simulations don’t quite behave as expected—energy plateaus, unrealistic geometries, or convergence issues.…

Tired of Static 2D Interaction Diagrams? Try This

OneAngstrom

For many molecular modelers, generating 2D diagrams of protein-ligand interactions is a foundational yet repetitive task. These diagrams are essential to illustrate key interatomic contacts, but customizing them to make them readable and publication-ready can feel like an endless layout…

A Quick Way to Give Your Molecular Models a Professional Look

OneAngstrom

Creating photorealistic molecular visuals can be time-consuming if each element needs to be manually styled. Whether you’re working on a publication figure, a presentation, or simply want to explore your models with more visual clarity, adjusting visual materials quickly and…
