Making Molecular Objects Disappear (and Reappear) with Precision

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,…

Creating Custom Index Groups for GROMACS Pulling Simulations in SAMSON

OneAngstrom

When performing molecular dynamics simulations with GROMACS, creating custom index groups is often a source of friction—especially for those performing pulling simulations. Manually generating index files (.ndx) using the GROMACS command line can be tedious and error-prone, particularly for users…

Making Molecular Animations Simpler with the ‘Show’ Effect

OneAngstrom

One of the challenges faced by many molecular modelers when preparing visualizations is controlling the timing and visibility of molecular components in animations. Whether you’re building an educational video, a research presentation, or simply exploring dynamic behavior, it can be…
