Selecting Atoms Like a Pro in SAMSON: An Introduction to NSL

When working with complex molecular systems, selecting atoms for visualization, editing, or analysis can quickly become overwhelming. Whether you’re developing a new molecule, importing data from experimental studies, or running simulations, you’ll often need to isolate parts of a system—like…

Stop Searching for Files: Streamline GROMACS Input Selection with Auto-Fill

OneAngstrom

Anyone working with molecular simulations knows the frustration of constantly navigating folders to locate the correct input files—especially when transitioning between simulation steps like energy minimization, NVT equilibration, and NPT equilibration. If you’re using the GROMACS Wizard in SAMSON, there’s…

Effortlessly Identify Hydrogen Bond Donors and Acceptors in Your Molecular Models

OneAngstrom

When modeling molecular systems, identifying hydrogen bond donors and acceptors quickly and accurately is often crucial. Whether you’re preparing structures for docking, analyzing interactions in a protein-ligand complex, or filtering atoms for visualization, being able to specify which atoms participate…

Quickly Find Specific Chains Using NSL in SAMSON

OneAngstrom

If you’re working with large biomolecular systems in SAMSON, it can become overwhelming to manage and analyze specific chains. Whether you’re editing, visualizing, or preparing systems for simulations, refining your selection to just the relevant molecular chains can save significant…

Avoiding Periodic Pitfalls: Setting Up the Box for COM Pulling in Molecular Simulations

OneAngstrom

When setting up a molecular dynamics (MD) simulation involving pulling, a frequent source of frustration among researchers is improper definition of the simulation box. The consequences? Artifacts due to periodic boundary conditions — from nonphysical interactions to misleading energy profiles.…

Filtering Aromatic Atoms, the Smart Way

OneAngstrom

Working with aromatic systems is an essential part of structure-based molecular modeling, from visualizing planar ring systems to performing conformational analysis on drug-like molecules. But selecting these atoms precisely can be time-consuming—especially when your molecules are large or complex. This…

Why Run GROMACS Simulations in the Cloud?

OneAngstrom

If you’ve ever run molecular dynamics simulations with GROMACS, you already know how demanding they can be in terms of computational resources. Long trajectories, multiple replicas, and fine-grained time steps can push even powerful workstations to their limits. But what…

Making Molecules Appear at Just the Right Moment

OneAngstrom

It’s a familiar scenario for many molecular modelers preparing visual presentations: you’re building a molecular animation and want specific atoms, molecules, or protein subunits to appear smoothly at a precise point in time. You don’t want them to fade in…

Visual Transitions in Molecular Presentations: Adding Background Interpolations

OneAngstrom

When preparing molecular animations, the clarity of your visuals often plays a key role in how your ideas are received. Whether you’re showing conformational changes, ligand docking, or a molecular mechanism, smooth transitions can greatly enhance viewer comprehension. One common…

Tired of Manual Plugins? Here’s How SAMSON Makes Extension Management Easier

OneAngstrom

For molecular modelers, customizing software to suit specific workflows often means managing a jungle of plugins and add-ons. Whether it’s downloading, installing, updating, or simply keeping track of versions—plugin management can be time-consuming and error-prone. SAMSON provides a different solution…
