Quickly Filter Molecular Animations with NSL Attributes in SAMSON

When working on molecular animations, molecular modelers often need to selectively visualize or analyze specific animation nodes based on their properties. However, navigating large molecular systems with multiple overlapping animations can get time-consuming and error-prone. This is where the Node…

Tracking Molecular Movement with Pathlines: Visualizing Center-of-Mass Trajectories

OneAngstrom

When working with molecular simulations, one recurring challenge is making sense of how parts of a molecular system move over time. Whether it’s a ligand unbinding from a protein pocket, a domain shift in a protein complex, or atoms diffusing…

Skip the Cluster Queue: Run GROMACS Simulations in the Cloud with SAMSON

OneAngstrom

If you’ve spent hours in a computing cluster queue or had to deal with installation issues for large molecular dynamics packages, you’re not alone. For many molecular modelers, especially those working in academic environments or on personal machines, accessing suitable…

Controlling the Flow of Your Molecular Animations: Introducing the Stop Effect

OneAngstrom

If you’ve ever tried to explain complex molecular phenomena through animations, you know how quickly things can move—sometimes too quickly for your audience to follow. Whether you’re teaching with molecular visualizations, presenting a research discovery, or crafting an educational video,…

Tweaking Bonds and Atom Types in UFF Simulations: What You Should Know

OneAngstrom

One of the recurring challenges in molecular modeling is ensuring that force field parameters truly reflect the intent behind your molecular system. Whether you’re refining a biomolecule or designing a novel compound, automatic parameterization tools can’t always know exactly what…

A Simple Trick to Record Trajectories for Molecular Presentations in SAMSON

OneAngstrom

When building molecular presentations or animations in SAMSON, there often comes a moment when you wish to record how atoms move—either to show a docking process, a simulation, or a molecular rearrangement. But manually tracking trajectories frame by frame? That’s…

Avoid Manual File Errors: Selecting Input Structures in NPT Equilibration

OneAngstrom

One common source of frustration in molecular dynamics workflows is accidentally using the wrong input file when transitioning between simulation stages. This becomes especially problematic during equilibration steps where mismatches can cause runs to crash or yield incorrect results. In…

Exporting Molecular Structures from SAMSON: What You Need to Know

OneAngstrom

When working on molecular modeling projects, exporting your results into the right file formats is a crucial step—whether you’re preparing datasets for collaborators, submitting to databases, or moving your models into other software tools. However, choosing the appropriate exporter, and…

Step-by-step approach to building a nanotube manually

OneAngstrom

Designing nanoscale structures like carbon nanotubes (CNTs) is a common task in nanotechnology and materials science, yet can be time-consuming using traditional modeling tools. One of the most frequent pains reported by molecular modelers is the difficulty in manually assembling…

From Fragment to Function: Registering Custom Monomers in SAMSON

OneAngstrom

Designing specific polymer architectures often starts with one fundamental step: defining your own monomers. For molecular modelers working on custom polymers, functionalized scaffolds, or bioconjugates, creating a library of reusable, well-defined repeat units can streamline workflows and minimize errors later…
