Easily Target Camera Nodes Using NSL in SAMSON

When working on complex molecular scenes in SAMSON, clarity is key. Whether you’re preparing a presentation, setting up multiple viewpoints, or scripting analyses, you often need to isolate and interact with camera nodes specifically. Unlike atoms or molecules, cameras have…

Stop Wasting Time on Broken Protein Structures: A Simple Guide to Preparing Protein Models in SAMSON

OneAngstrom

If you’re working with experimental protein data, chances are your structure files come with imperfections: alternate locations, missing atoms, ligands you don’t need, or solvent cluttering your simulation. For molecular modelers, preparing the system properly is not just optional—it’s the…

Choosing the Right Symmetry Group in Large Molecular Assemblies

OneAngstrom

When working with complex biological assemblies—like viral capsids or symmetrical protein complexes—one of the recurring challenges in molecular modeling involves identifying and exploiting symmetry. Symmetry helps reduce computational costs, validate structure quality, and guide the design of biomolecular nanostructures. But…

Why Running GROMACS on the Cloud Can Save You Time and Headaches

OneAngstrom

If you’ve ever tried to simulate a large molecular system using GROMACS, you’ve probably run into limitations on your local machine. RAM usage, simulation time, or even GPU availability can quickly become bottlenecks. Fortunately, the GROMACS Wizard extension in SAMSON…

Keeping Everything Together: Embedding Files and Folders in Molecular Documents

OneAngstrom

When working on complex molecular modeling projects, keeping all your related files—scripts, datasets, and supplementary materials—organized and in the right place can be a challenge. Molecular modelers often juggle structural data, downloadable database entries, computational scripts, and even research papers…

One Workflow, Many Molecules: Streamlining Batch Molecular Dynamics with SAMSON

OneAngstrom

Running molecular dynamics (MD) simulations across multiple systems can be one of the most time-consuming bottlenecks in molecular modeling. If you’ve ever found yourself repeating the same preparation and simulation steps manually for dozens of protein-ligand systems, you likely know…

Struggling to Align Molecular Structures? Here’s a Simple Way to Do It in SAMSON

OneAngstrom

Many molecular modelers know the frustration: you load a ligand or protein into your modeling environment and need to align it properly in 3D space—maybe for comparison, maybe for analysis, or maybe just to organize a complex scene. But trying…

Tidy Up Your Molecular Workspace with Node Group Selection Flags

OneAngstrom

When working with complex molecular systems, it doesn’t take long before your document in SAMSON fills with an overwhelming number of nodes—atoms, molecules, groups of molecules, visual models, annotations. Organizing and selecting them effectively can quickly become a challenge, especially…

Minimizing Only a Part of a Molecule in SAMSON: A Better Way to Adjust Structures

OneAngstrom

A common challenge in molecular modeling is the need to make small, precise changes to a structure without affecting the overall geometry. Whether you’re adjusting a functional group, refining a ligand conformation, or modifying only part of a large system,…

Loading Custom GROMACS Parameters Without the Guesswork

OneAngstrom

Researchers working with molecular dynamics simulations often need to rely on specific configuration files to fine-tune the behavior of simulation engines like GROMACS. Among these configurations, the .mdp file (Molecular Dynamics Parameters file) plays a central role. However, editing or…
