When You Need Atoms to Disappear: Animating Molecular Concealment in SAMSON

In molecular modeling and simulations, visualizations are essential for storytelling. Whether you’re preparing a conference talk, sharing a molecular mechanism on social media, or teaching students about molecular interactions, how you present your model can affect understanding and engagement. One…

Too Many Atoms? Create Custom Index Groups for Sanity

OneAngstrom

Anyone working with molecular dynamics (MD) simulations knows the pain: you’re ready to analyze some subtle motion or apply restraints during your GROMACS run, and the default index groups just won’t cut it. You need something specific — a pocket,…

Quickly Find Molecular Models by Atom Counts in SAMSON

OneAngstrom

Working with large molecular systems often means navigating through complex structures and disorganized data. Whether you’re analyzing biomolecules, designing nanostructures, or handling materials simulations, you’ve probably faced this challenge: how do I quickly locate specific models or folders based on…

Are Your Molecules Really Visible? Understanding Visual and Selection Flags in SAMSON

OneAngstrom

When working with complex molecular models, it’s not uncommon to spend precious minutes (or longer) trying to figure out why a molecule doesn’t show up in your scene or stays stubbornly excluded from selections. In the SAMSON molecular design platform,…

What Are Node Types in SAMSON, and Why Do They Matter in Molecular Modeling?

OneAngstrom

When building or analyzing molecular systems, researchers often have to manage highly complex structures composed of atoms, residues, chains, groups, and all sorts of simulation elements. Managing these efficiently is critical to working with large or dynamic molecular models. That’s…

Need to Zoom In Without Breaking Your Focus? Try the Zoom Camera Animation in SAMSON.

OneAngstrom

When preparing molecular animations, especially for presentations or publications, clarity is everything. A common frustration among molecular modelers is trying to zoom in on a specific part of a system — such as a binding site or a reaction center…

Quickly Select Side Chains Based on Attributes in SAMSON

OneAngstrom

When working with large molecular structures, isolating specific parts of interest—such as side chains with certain atomic properties—can save significant time. This is especially true if you’re preparing simulations, analyzing interactions, or cleaning up your models. In SAMSON, the Node…

A Quick Way to Instantly Enhance Molecular Visualizations in SAMSON

OneAngstrom

When working with complex molecular systems, presentation matters. Whether you’re preparing visuals for a publication, a lecture, or simply navigating intricate molecular networks, creating compelling representations that are both meaningful and accessible can take time. 👍 This is where Visual…

Controlling Molecular Scene Appearance with Render Preset Attributes

OneAngstrom

When you’re dealing with molecular modeling, presentation isn’t just aesthetic—it’s essential. Whether you’re preparing visuals for publication, sharing models with collaborators, or trying to quickly identify certain features in a complex scene, controlling how each part of your system is…

Making PMF Calculations Less Painful with GROMACS Wizard

OneAngstrom

If you’ve ever run umbrella sampling simulations in molecular dynamics, you probably know the next step: extracting the Potential of Mean Force (PMF) to understand free energy profiles along a reaction coordinate. But actually going from simulation data to a…
