Speeding Up Molecular Visualization with Custom Visual Presets

Setting up visualizations for complex molecular systems often takes time—especially when you want consistent style, clarity, and precision across multiple structures or sessions. Whether you’re preparing a publication figure, exploring protein-ligand interactions, or showing a dynamic process to students, you’ve…

Making Molecular Presentations Feel Like Slides

OneAngstrom

When preparing presentations for molecular modeling work, researchers often face the challenge of controlling the pace of their animations. Whether you’re demonstrating a binding process, highlighting conformational changes, or transitioning between topics in a research talk, timing is critical. A…

Simplify Your Molecular Modeling Workflow by Customizing the SAMSON Interface

OneAngstrom

When working on complex molecular systems, staying organized and minimizing distraction is key. Many molecular modelers struggle with cluttered interfaces or inefficient workflows because the tools they use don’t adapt to how they think or work. Fortunately, SAMSON offers extensive…

Always Keep Your Eyes on the Molecule: Using the ‘Look at atoms’ Animation in SAMSON

OneAngstrom

When working with molecular dynamics or structural analysis, it can be frustrating to lose track of a key region in your model just because the camera drifts away during visualization. Whether you are analyzing a binding site over time or…

Synchronizing Your Views: A More Intuitive Way to Work with Molecular Sequences

OneAngstrom

For many molecular modelers, managing complex biomolecular systems means jumping between multiple representations: 3D structures, sequences, and data tables. A frequent source of friction is the disconnect between these representations—particularly when selecting elements in one view doesn’t immediately reflect in…

How to Create Custom Index Groups in GROMACS Wizard Without Writing a Line of Code

OneAngstrom

When running advanced molecular dynamics simulations, especially those involving pull groups or complex post-simulation analysis, it’s often necessary to define custom index groups. This is typically done using gmx make_ndx, which requires knowledge of GROMACS command-line syntax and selection strings.…

When Steepest Descent Isn’t Enough: Accelerating Molecular Relaxation with FIRE

OneAngstrom

Geometry optimization is an essential step in molecular modeling workflows, whether you’re preparing initial configurations for simulations or cleaning up experimental structures. But if you’ve ever felt that your steepest descent minimizer just isn’t converging fast enough—especially in systems with…

Make sense of molecular visualizations by filtering visible nodes in SAMSON

OneAngstrom

If you’ve ever worked on a large molecular system, you know how cluttered the visual scene can become. Whether you’re analyzing docking results, molecular dynamics trajectories, or assembling molecular systems, excessive visual complexity often slows down interpretation and leads to…

Avoid Solvent Clashes in Coarse-Grained MD Simulations by Adjusting van der Waals Distances

OneAngstrom

One common frustration for molecular modelers preparing coarse-grained (CG) systems for molecular dynamics simulations is dealing with solvated structures where solvent beads overlap with solute atoms. These clashes often cause failed simulations or unphysical behavior. The root cause? The default…

A Practical Guide to Covalent Docking with the FITTED Suite in SAMSON

OneAngstrom

Covalent docking is a powerful strategy in structure-based drug design, especially when targeting active sites with known reactive residues. However, setting things up properly — from hybridization to binding site specification — can be a major source of friction for…
