Filtering Node Groups by Selection State in SAMSON

If you’ve worked with complex molecular systems in SAMSON, you’ve likely faced the challenge of isolating particular groups of atoms or molecular components. This becomes especially relevant when dealing with large biomolecular assemblies or simulations with numerous nodes. One of…

Molecular Modeling Isn’t Easy—But SAMSON’s Interactive Tutorials Make It Simpler

OneAngstrom

For many molecular modelers, the early stages of using a new software platform can feel like learning a foreign language. From navigating a complex interface to figuring out how to run simulations or analyze data, the learning curve can be…

Working with Molecular Dynamics Trajectories in SAMSON

OneAngstrom

Molecular modeling and simulation often involve handling large trajectory files produced by molecular dynamics engines like GROMACS, AMBER, NAMD, LAMMPS, and Tinker. However, switching between simulation and visualization tools can feel like constantly battling with incompatible data formats and slow…

Avoiding Costly Mistakes with the History Feature in SAMSON

OneAngstrom

It’s happened to every molecular modeler: hours spent refining a complex structure, carefully adjusting geometry or interaction parameters, only to lose a crucial state after a slip of the mouse or an unexpected action. For those using SAMSON, the integrative…

Bring Your Own Code: Integrate External Tools into SAMSON Easily

OneAngstrom

Many researchers and developers in molecular modeling rely on custom scripts, external executables, or web services to perform specific tasks—such as docking, calculations, or data analysis. However, managing multiple tools can be time-consuming, especially when interoperability isn’t seamless. This is…

Quickly Select and Show Only What Matters in Your Molecular Scene

OneAngstrom

When your molecular scene becomes crowded with visual models, it’s easy to lose focus. Whether you’re preparing images for publication, analyzing a specific interaction site, or debugging a custom SAMSON app, you likely spend time toggling visibility and manually sifting…

How to Quickly Target File Nodes in SAMSON with NSL Filters

OneAngstrom

Managing large molecular projects in SAMSON? If you’ve ever found your workspace filled with dozens of files, and struggled to apply filters or actions only to specific file nodes (and not the nodes inside them), you’re not alone. This is…

Make Molecules Fade, Not Teleport — Disappearing Objects in SAMSON

OneAngstrom

If you’ve ever built an animation of a molecular system and felt frustrated by the sudden disappearance of elements—like they just vanish from the scene without context—you’re not alone. Molecular modelers often need to visually transition elements out of view…

Tired of Repeating Molecular Simulations? Use Batch Projects in SAMSON

OneAngstrom

If you’ve ever run molecular dynamics simulations for multiple conformations of the same molecule, you know how tedious it can be to repeat the same setup steps over and over. Whether you’re iterating through a ligand binding pathway or comparing…

Paths vs. Conformations: Which to Use with the P-NEB Method in SAMSON?

OneAngstrom

When modeling molecular transitions such as ligand unbinding or conformational changes in biomolecules, predicting realistic pathways is often critical, but far from straightforward. Finding the most efficient and accurate approach can save time and computing resources, especially when working with…
