Hidden or Shown? Managing Visibility in Molecular Models the Clear Way

As a molecular modeler, you’ve likely experienced the challenge of navigating complex molecular systems filled with overlapping nodes, materials, and annotations. Whether you’re visualizing conformational changes or preparing a figure for publication, being able to quickly control what’s visible in…

Fixing Protein Backbone Outliers: A Visual Approach with the Ramachandran Plot

OneAngstrom

Protein modeling often runs into a simple yet nagging issue: some residues don’t conform to expected backbone geometries. These structural outliers can affect downstream simulations or reduce the quality of homology models—especially when small deviations escape plain sight. Fortunately, there’s…

Avoid Repetitive Setup with Custom Index Groups in GROMACS Wizard

OneAngstrom

For molecular modelers working with complex systems in GROMACS, organization and reproducibility can become a challenge—especially when the same custom selections need to be defined across multiple stages or subprojects. Whether you are preparing simulations or running batch workflows, manually…

How to Define and Connect Custom Monomer Sequences in SAMSON’s Polymer Builder

OneAngstrom

When designing polymers for simulations or material property prediction, it’s often essential to define precise patterns of monomers: not just their identity but the way they connect. This is particularly true if you’re modeling complex materials, conjugated compounds, or drug-polymer…

Simulating physical behavior while preserving atomic constraints in SAMSON

OneAngstrom

When modeling nanosystems, researchers frequently face the challenge of keeping parts of the system fixed or following a pre-defined motion, while letting others evolve naturally according to physical laws. This is often the case when simulating mechanical systems like molecular…

Making Molecular Presentations Flow: How to Set Background Transitions in SAMSON

OneAngstrom

If you’ve ever presented molecular models and found the transitions between slides or states too abrupt, you’re not alone. A typical challenge in molecular modeling presentations is maintaining visual continuity. This is especially true when you’re demonstrating conformational changes, structural…

Selecting Residues from Sequence View in SAMSON: A Timesaver for Molecular Modelers

OneAngstrom

When working with large biomolecular structures, one of the most frequent—and often frustrating—tasks is precisely selecting specific residues or residue ranges. Whether you’re defining regions for simulation, modifying part of a protein, or analyzing interactions, doing this in the 3D…

Saving Time in Molecular Simulations: Setting Up Multiple Conformations in One Go

OneAngstrom

Running molecular dynamics simulations on multiple conformations of the same molecule—whether to sample different initial states or to conduct techniques like Umbrella Sampling—can be necessary but very repetitive. If you’ve ever found yourself manually preparing each structure, adjusting box sizes,…

Quickly Find Large Conformations Using the NSL

OneAngstrom

When working on complex biomolecular systems, it’s not always easy to stay organized. One common challenge molecular modelers face is identifying specific conformations of interest from large sets of data. For example, you may want to isolate conformations that contain…

Tired of Searching Menus? Try Natural Language Commands in SAMSON

OneAngstrom

If you spend a significant portion of your day exploring molecular models, you’ve likely lost time navigating complex menus, toggling panels, or trying to remember tool names. This friction breaks flow and adds an unnecessary cognitive load. With SAMSON AI,…
