Choosing the Right Colors for Molecular Models: Discrete Palettes in SAMSON

When working with complex molecular models, color plays a bigger role than you might think. Color can help distinguish between molecular groups, highlight structural features, and enhance overall legibility—particularly in presentations, publications, or educational content. But picking colors manually can…

A Safer Way to Apply Custom MDP Parameters in SAMSON’s GROMACS Wizard

OneAngstrom

Applying custom simulation parameters in molecular dynamics (MD) workflows allows researchers to fine-tune their systems for specific scientific goals. But it can also lead to unexpected problems if those parameters are inconsistent or improperly set, especially when copied from other…

Why Only One Editor is Active at a Time in SAMSON

OneAngstrom

For molecular modelers working with complex systems, a major challenge is managing various tools and functionalities without overwhelming the user interface. If you’ve ever wondered why SAMSON allows only one editor to be active at any given time, you’re not…

Getting Precise with Your Selections in SAMSON’s Document View

OneAngstrom

For molecular modelers working with complex systems, selecting exactly the right groups of atoms, residues, or molecular fragments is often a repetitive and time-consuming task. Whether you’re preparing systems for simulation, analyzing interaction networks, or visualizing specific components, it can…

Quickly Find Hidden or Visible Models Using NSL in SAMSON

OneAngstrom

If you are working with large molecular systems in SAMSON, you’ve probably faced the challenge of visual clutter. Hundreds of model nodes – some visible, some hidden, and many buried under layers of data. When you’re trying to focus on…

Selecting atoms with natural language in SAMSON AI

OneAngstrom

Molecular modeling involves frequent selection of specific atoms, residues, chains, ligands, or binding sites. This task can become tedious and error-prone, especially in complex molecular systems. Traditional selection tools involve dropdowns, checkboxes, or writing selection syntax. Not only does this…

Quickly Identify Bonds by Type in Your Molecular Models

OneAngstrom

When working with complex molecular structures, it’s often necessary to inspect or refine specific bond types, such as identifying only the aromatic bonds in a protein-ligand complex or checking for unusual bond patterns in generated conformers. This task, usually time-consuming…

Watching the SARS-CoV-2 Spike Move: A Useful Trajectory for Molecular Modelers

OneAngstrom

Modeling conformational changes in large biomolecular assemblies is a recurring challenge in structural biology and drug design. One protein that drew intense focus is the SARS-CoV-2 spike, which transitions between closed and open states to interact with the ACE2 receptor.…

Why You Can Only Use One Editor at a Time in SAMSON

OneAngstrom

While working on molecular models, users often wish to interact with structures in more than one way—perhaps selecting atoms, applying transformations, and generating nanostructures all in succession. In SAMSON, this flexibility is achieved through Editors: tools designed to help you…

Avoid Solvent Clashes in GROMACS CG Simulations with One Simple Tweak

OneAngstrom

When setting up coarse-grained (CG) molecular dynamics (MD) simulations in GROMACS using the MARTINI force field, one of the most common frustrations is solvent clashes. These issues often arise not from user error, but from a default behavior: GROMACS applies…
