How to Quickly Control Visibility of Animation Nodes in SAMSON

In molecular modeling, animation allows researchers to visualize transitions, dynamics, or structural variations over time. But as these animations grow complex, managing visibility within molecular environments becomes a tedious task—especially when working with hundreds of nodes simultaneously. That’s where SAMSON’s…

Integrate Your Own Tools into SAMSON with Custom Apps

OneAngstrom

For many molecular modelers, a recurring challenge is the dispersion of tools across multiple platforms. You might be using different software for docking, visualization, analysis, and data access. Each tool has its strengths, but switching between them adds friction to…

A Quick Way to Reuse Custom GROMACS Parameters in SAMSON

OneAngstrom

For molecular modelers working with GROMACS, managing molecular dynamics parameters across different simulation steps can be a time sink. If you’re frequently switching between projects, tuning parameters, or experimenting with different equilibration conditions, then manually reconfiguring parameter sets for each…

Stop Scrolling. Use NSL to Find Exactly the Nodes You Need.

OneAngstrom

Molecular modelers often spend excessive time manually navigating complex molecular documents just to select or isolate the nodes they are interested in. Whether you’re trying to highlight a ligand, isolate a group of residues, or analyze a subset of hydrogens,…

Why Your Molecular Files Won’t Open — And How to Fix It in SAMSON

OneAngstrom

If you’ve ever tried to open a structure file in your molecular modeling software and been met with a blank screen or an error message, you’re not alone. Molecular modelers often work with a wide variety of file formats—PDB, mmCIF,…

How Node Group Attributes Can Help You Organize Molecular Models Better

OneAngstrom

When working on complex molecular models, it doesn’t take long before your document becomes cluttered with atoms, residues, molecules, and larger structural elements. One underused — but highly effective — way to keep things organized in SAMSON is by leveraging…

From Clicks to Code: Writing Python Scripts with SAMSON AI

OneAngstrom

When working on molecular modeling projects, many researchers face a common challenge: repetitive, manual tasks that cost time and lower reproducibility. Whether it’s translating structures, computing simple properties, or automating a workflow, scripting offers a way out—if you know how…

Drawing Nanotubes with a Mouse: Interactive CNT Modeling in SAMSON

OneAngstrom

Molecular modelers working with carbon nanotubes (CNTs) often need to generate structures quickly to test ideas, verify hypotheses, or initiate simulations. However, many tools place barriers such as command-line syntax, abstract parameters, or pre-baked models that don’t reflect exact needs.…

Running GROMACS Simulations in the Cloud with SAMSON

OneAngstrom

One common challenge for molecular modelers is performing large-scale or lengthy GROMACS simulations without overloading their local machines. Interactive work becomes sluggish, fans spin up, and background simulations may suddenly halt if the system goes idle or reboots. What if…

Avoiding Pitfalls in Coarse-Grained MD: Setting Up Solvents and Ions Correctly

OneAngstrom

One of the most overlooked yet crucial steps in preparing coarse-grained molecular dynamics (MD) simulations is solvent and ion setup. If coarse-grained (CG) models are incorrectly solvated or ionized, simulations often produce unrealistic results—or fail entirely. This blog post focuses…
