Avoid Polymer Frustration: A Simple Way to Define Custom Monomers

Building polymers in molecular modeling often starts off fine—until you hit the roadblock of customization. Maybe you’re designing a novel material, exploring backbone flexibility, or preparing conjugated architectures. But when it’s time to define your own monomers, many existing tools…

Easily Align Molecular Structures in SAMSON’s Global Reference Frame

OneAngstrom

Precise orientation of molecular models is essential in many modeling workflows, from preparing simulations and comparing molecular structures to generating reproducible visualizations. Yet, achieving consistent alignment can be tedious, especially when done manually. If you’re working with molecular structures, meshes,…

Less Eye Strain, More Molecular Insight: Choosing Color Palettes You Can Trust

OneAngstrom

If you’ve ever struggled to distinguish between important parts of a molecular model due to color confusion or visual overload, you’re not alone. A common pain point in molecular modeling is using color schemes that are either too harsh, too…

Creating Custom Index Groups in SAMSON for Smarter GROMACS Simulations

OneAngstrom

When running molecular simulations with GROMACS, organizing parts of your system into logical groups can make a huge difference in analysis and setup—especially if you need to define regions of interest like specific residues or structural motifs. In GROMACS terminology,…

Quickly Find Hidden or Visible Structures in SAMSON Using NSL

OneAngstrom

If you’ve worked with complex molecular systems, chances are your document becomes cluttered with multiple structural models. Models become hidden, toggled on and off, or simply lost in a forest of atoms and molecules. If you’ve asked yourself, “Which of…

How to Quickly Identify Metal Atoms in Your Molecular Model

When you’re examining complex molecular systems, identifying metallic elements—especially transition metals and their neighbors—can be essential. Whether you’re studying a metalloprotein, researching catalysis, or preparing a molecular dynamics simulation, isolating metal atoms quickly saves time and reduces errors. In this…

A Simpler Way to Run GROMACS Simulations Without Local Hardware

OneAngstrom

Running molecular dynamics (MD) simulations can take a significant toll on local hardware, especially when simulating large systems or running long trajectories. Many researchers face the challenge of not having access to high-performance computing infrastructure when they need it most.…

When Zooming Isn’t Enough: Using Dolly Camera Animation in Molecular Visualizations

OneAngstrom

When working with complex molecular structures, showing the right detail from the right angle can change everything. Whether you’re preparing content for a presentation, teaching a concept, or demonstrating a simulation result, camera motion matters. A lot. One common obstacle…

Troubleshooting Unstable Densities During NPT Equilibration in SAMSON

OneAngstrom

One of the most frustrating issues for molecular modelers using GROMACS is running an NPT equilibration—only to find that the system’s density is still oscillating or far from expected. If you’re spending time wondering whether you need to restart, modify…
