Bringing Molecular Trajectories to Life with Play Path Animations

One of the most common challenges faced by molecular modelers is visualizing changes in molecular conformations over time. Whether you’re working with molecular dynamics (MD) simulations, conformational sampling, or interactive modifications, seeing how a system evolves in space and time…

Quickly Filter Visible and Hidden Elements in Molecular Models

OneAngstrom

When working with complex molecular systems in SAMSON, clarity is often the first casualty. Visual clutter created by overlapping atoms, surfaces, and annotations can make it difficult to focus on the relevant parts of your simulation or analysis. Navigating through…

How to Keep Functional Waters and Delete the Rest in Biomolecular Simulations

OneAngstrom

When preparing biological systems for molecular dynamics simulations, one recurring pain point is deciding what to do with water molecules. Should you delete all of them? What if some are tightly bound and essential for protein function or ligand binding?…

Prevent unwanted camera drift when animating molecular systems

OneAngstrom

When creating animations of molecular systems, you’re often focused on illustrating detailed transitions—like conformational changes, ligand docking, or energy minimizations. But there’s a subtle issue that many researchers encounter: the camera viewpoint can drift between frames unintentionally, especially if no…

Streamline Your Molecular Workflow with SAMSON AI’s Python Scripting

OneAngstrom

Writing Python scripts for molecular modeling often involves switching between documentation, coding environments, and visualization tools. For researchers and students working with complex simulations, simple tasks—like transforming atoms or building interfaces—can become time-consuming due to repetitive coding and context switching.…

Quickly Select Atoms by Geometry with NSL in SAMSON

OneAngstrom

When modeling molecules, filtering atoms by chemical properties or structural features is an everyday task. Yet, for many molecular modelers, selecting atoms by geometry—like tetrahedral or octahedral configuration—can still be a tedious, time-consuming process, especially when working with large systems.…

Exporting Ligand Trajectories for Free Energy Calculations in SAMSON

OneAngstrom

Preparing input files for free energy calculations can often be tedious, requiring custom scripts to extract atomic coordinates along a reaction path. Fortunately, SAMSON’s Export Along Paths extension streamlines this task through a user-friendly interface that allows you to export…

Refining Ligand Unbinding Pathways: A Step-by-Step Guide Using P-NEB in SAMSON

OneAngstrom

In molecular modeling, finding biologically relevant transition pathways between molecular states can be a challenge—especially when simulating ligand unbinding events. Often, you may already have a trajectory generated through sampling or interpolation, but need to make it more accurate from…

Before You Simulate: The Smart Way to Clean Up Molecular Geometries

OneAngstrom

When preparing molecular systems for simulation, clean geometry isn’t optional—it’s essential. Poor atomic arrangements can lead to unrealistic behavior, convergence failures, or wasted compute time. That’s why optimizing geometries before launching simulations should be part of every molecular modeler’s workflow.…

Keeping Molecules Still for Better Animations

OneAngstrom

When working on molecular animations, one of the most common frustrations that molecular modelers face is keeping parts of a molecule steady while the rest of the system moves. Whether you’re showcasing ligand docking, domain movement, or assembling large biomolecular…
