Visualizing the SARS-CoV-2 Spike in Motion: A Molecular Animation Pipeline

One of the most common difficulties faced by molecular modelers is how to generate meaningful animations of conformational transitions between known protein states—especially when those states do not perfectly match in residue count or structure. Such animations are invaluable for…

Stop Wasting Time on Invisible Molecular Data: Use visibility flags the smart way

OneAngstrom

When working with large and complex molecular systems, it’s common to hide parts of the model to reduce visual clutter or focus on a specific region. But if you’ve ever found it confusing to manage visibility in SAMSON, especially when…

How to Precisely Select Structures with NSL in SAMSON

OneAngstrom

Selecting specific molecular components can often feel overwhelming when working on large macromolecular complexes. You might be looking to isolate only atoms in ligands, or visualize hydrogens within water molecules. Knowing how to express those search criteria accurately can save…

A Faster Way to Build Carbon Nanotubes Visually

OneAngstrom

Creating carbon nanotube (CNT) models can be time-consuming if you’re constrained by parameter entry forms and repetitive manipulation steps. Molecular modelers often need to generate and iterate through multiple CNT geometries before locking one down for simulations. But what if…

A Simple Way to Query File Nodes in Your Molecular Models

OneAngstrom

When working with complex molecular systems in SAMSON, it’s common to handle multiple datasets, simulations, or structural variations, each encapsulated in distinct file nodes. Whether you’re juggling docking runs or importing external molecular files, a recurring need arises: how do…

Defining Custom Monomers for Smarter Polymer Design

OneAngstrom

Designing complex polymers with specific properties often starts with the simplest building block: the monomer. But if you’ve ever needed to go beyond standard monomer libraries to define your own, you know how tedious that process can be in many…

Easily Select Negatively Charged Residues (And Other Filters) in SAMSON with NSL

OneAngstrom

When working with macromolecular structures, a common challenge for molecular modelers is to efficiently identify and manipulate residues that meet specific biochemical or structural criteria. Whether you’re preparing a protein for simulation, adjusting protonation states, or studying interactions near active…

When Structures Let Go: Introducing the Undock Animation in SAMSON

OneAngstrom

In molecular modeling, visual storytelling plays a surprisingly important role. Whether you’re preparing a scientific talk, teaching structural biology, or simply trying to understand how two molecules interact—or stop interacting—animation can provide clarity that static images often can’t. One common…

When Zooming Isn’t Enough: Using Dolly Camera Animation in SAMSON

OneAngstrom

When working on molecular systems, being able to clearly communicate what you are seeing is just as important as understanding what you are looking at. Capturing smooth transitions for presentations, tutorials, or publications can be a challenge, especially when you…

Quickly Switch Between Molecular Selections with Quick Groups in SAMSON

OneAngstrom

When working on complex molecular systems — such as proteins with multiple ligands, solvated complexes, or multimeric structures — it’s common to revisit specific components repeatedly. Selecting a ligand, then moving to a receptor, and later examining water molecules or…
