What to Look For After Energy Minimization in GROMACS Wizard

Energy minimization is a key step in the molecular dynamics workflow. It helps to remove steric clashes or geometric problems in your molecular model before moving on to more computationally intensive stages like equilibration and production runs. But after clicking…

Making Atoms Fade Out Gracefully: A Look at the Disappear Animation in SAMSON

OneAngstrom

When preparing molecular animations to communicate modeling results, clarity and visual progression are key. Whether you’re recording a molecular dynamics simulation or simply creating a narrated presentation for a classroom or conference, transitions help guide viewers’ attention. One transition that’s…

Easier Visual Validation: Smoothly Undock Molecular Groups with SAMSON

OneAngstrom

Communicating molecular mechanisms clearly is a recurring challenge for molecular modelers, especially when presenting ligand-receptor interactions, docking pathways, or structural transitions. One simple but often overlooked pain point is illustrating how a ligand undocks from its receptor. This step is…

Eyes Getting Tired? Switch to Dark Mode in SAMSON

OneAngstrom

Staring at molecular structures for hours can be demanding, especially when working late or in low-light environments. If you’ve ever found yourself squinting at a brightly-lit interface while modeling proteins, docking ligands, or adjusting rendering settings, you’re not alone. Dark…

Why Your Molecular Modeling Extension Might Not Load (and What To Do About It)

OneAngstrom

When a SAMSON Extension doesn’t load, it’s easy to assume something is wrong with your system or the extension itself. But in many cases, the issue boils down to one thing: version compatibility. This post unpacks how SAMSON checks compatibility…

Avoiding Solvent Clashes in Coarse-Grained Simulations with GROMACS Wizard

OneAngstrom

When setting up coarse-grained (CG) systems for molecular dynamics simulations with GROMACS, one common source of instability and frustration is poor solvation—especially when solvent molecules are placed too close to solute atoms, causing steric clashes. Fortunately, SAMSON’s GROMACS Wizard offers…

Making Molecular Data Understandable: A Practical Guide to Visual Models in SAMSON

OneAngstrom

Visualizing molecular systems effectively is one of the key challenges faced by scientists, researchers, and educators working in structural biology, drug design, and materials science. Molecules are complex, and meaningful insights often depend on being able to visualize relevant structures…

Quickly Identify Side Chains with Missing Materials in SAMSON

OneAngstrom

Molecular modelers often work with large biomolecular systems, such as proteins, and need a quick way to detect modeling issues that could affect visualization, analysis, or simulation. One commonly overlooked issue is the presence of side chains lacking material definitions—the…

Custom Atom Groups in GROMACS Simulations: A Quick Way to Save Time and Simplify Analysis

OneAngstrom

When setting up molecular dynamics simulations, small frustrations can have a big impact—especially when it comes to defining groups of atoms for analysis or pulling simulations. By default, GROMACS defines standard index groups such as proteins, water, and ions. But…

From SMILES to 3D Structures in a Few Clicks

OneAngstrom

One of the most common and time-consuming tasks in molecular modeling is generating accurate 3D molecular structures from SMILES (Simplified Molecular Input Line Entry System) strings. Whether you’re preparing datasets for simulations, virtual screening, or property prediction, the process often…
