Making Molecules Breathe: A Visual Trick to Enhance Structural Transitions

Clarity and visual communication are major challenges in molecular modeling. When crafting animations to illustrate complex molecular phenomena—such as binding events, structural adjustments, or phase transitions—it’s common to feel limited by basic visualization tools. Animations can quickly become cluttered or…

Avoiding Clashes When Solvating Coarse-Grained Systems in GROMACS

OneAngstrom

Working with coarse-grained (CG) models is a common strategy for simulating larger molecular systems with reduced computational cost. However, when preparing these systems for molecular dynamics (MD) simulations, one subtle but critical issue often trips up even experienced modelers: the…

Making Molecular Objects Disappear (and Reappear) with Precision

OneAngstrom

In molecular modeling, clear communication is essential. Whether you’re presenting a mechanism to collaborators or preparing a visual for publication, controlling the visibility of molecules or molecular fragments at specific times can dramatically improve audience understanding. This is where the…

Creating Custom Molecular Interactions in SAMSON Without Coding

OneAngstrom

Being able to define and manipulate molecular interactions is essential when designing or analyzing molecular systems. From modeling hydrogen bonds to setting up protein–ligand docking environments, molecular modelers frequently need to go beyond visualization and directly interact with the system.…

Making Molecular Models Move: How to Use the Undock Animation in SAMSON

OneAngstrom

When preparing a molecular animation or visualizing a docking scenario, one common challenge modelers face is illustrating the actual undocking process of ligands, proteins, or other structural components. Creating this visualization manually could take a significant amount of time and…

Filtering Molecular Structures by Atom Counts in SAMSON

OneAngstrom

If you’ve ever worked with large molecular datasets, you know how valuable it is to filter and select structures based on their composition. Whether you’re modeling organic molecules, studying reaction mechanisms, or analyzing biomolecular systems, identifying specific groups based on…

Dragging Atoms, Watching Molecules Respond: A Closer Look at Interactive Simulation in SAMSON

OneAngstrom

Simulating molecular movement is a core task for many researchers, but getting immediate feedback from changes made in a visual editor is often time-consuming or unavailable altogether in some tools. One common pain point in molecular modeling is not being…

Visualizing Atomic Defects in Diamond Structures with SAMSON

OneAngstrom

Crystals may seem perfect in textbooks, but in the real world, they’re far from flawless. Atomic defects—tiny irregularities in the structure—can have dramatic effects on material properties like conductivity, strength, and color. For molecular modelers and materials scientists, simulating and…

Filtering Molecules by Functional Groups: Substructure Search with the SMILES Manager

OneAngstrom

When working with molecular libraries, identifying subsets of molecules that contain specific functional groups can be both repetitive and error-prone. Whether you’re hunting for fluorinated compounds, analogs with nitrogen-containing backbones, or custom motifs for SAR analysis, manual filtering isn’t scalable.…

Why Your Molecular Modeling Plugin Won’t Load (And How to Fix It)

OneAngstrom

If you’re developing or using custom extensions in SAMSON for your molecular modeling projects, you may have run into this: a SAMSON Extension won’t load at startup, even though it worked perfectly fine before. No error message is immediately helpful,…
