Quickly Isolate Conformations with Over 100 Atoms in SAMSON

When working with complex molecular systems, molecular modelers often face the challenge of navigating and managing large numbers of conformations. Some conformations may only contain a few atoms, others might represent larger fragments or complete molecules. If you’re trying to…

Quickly Find Charged Groups in Your Molecular Models

OneAngstrom

When exploring large molecular systems in SAMSON, identifying charged structural groups can be a repetitive and time-consuming task. Whether you’re validating a simulation setup, preparing a biomolecular system, or quickly inspecting charged fragments, having an easy way to filter and…

Dragging Atoms, Watching Molecules Respond: A Beginner’s Guide to Interactive Simulation in SAMSON

OneAngstrom

One common frustration in molecular modeling is the disconnect between model manipulation and immediate feedback. Molecular designers frequently spend time adjusting structures and running batch simulations, only to repeatedly refine parameters through a slow trial-and-error cycle. What if changes could…

Tired of clicking atoms one by one? Learn how to search smarter with NSL.

OneAngstrom

When dealing with complex molecular systems, manually selecting atoms, residues, or ligands can quickly become tedious—even frustrating. If you’ve ever found yourself zooming and clicking around just to isolate one component of a protein-ligand complex, this post is for you.…

Why NVT Equilibration Still Trips People Up (and How to Avoid Common Setup Issues)

OneAngstrom

Equilibration in molecular dynamics is an essential step before launching production simulations. But even experienced molecular modelers sometimes hit snags during the NVT (constant particle number, volume, and temperature) equilibration phase. This blog post explores how to avoid common setup…

Making Collaboration Easier: How to Control Access to Your Molecular Design Documents

OneAngstrom

When working on molecular design projects, sharing results and configurations across a team can be both essential and challenging. Whether you’re collaborating with researchers in your lab, students, or external contributors, it’s important to provide access to the right documents…

Step-by-step nanotube construction using SAMSON’s Pattern Editors

OneAngstrom

Creating carbon nanotubes is a common task in nanoscale design. Despite being conceptually simple, the manual construction of these tube-like structures with regular periodicity, seamless curvature, and proper bonding alignment can be time-consuming and technically tricky — particularly when high…

Working with Many Conformations at Once in Molecular Simulations

OneAngstrom

Running simulations on a single molecular structure is common practice, but what if you have many starting conformations of the same molecule? Whether you’re studying flexibility, rare events, or preparing umbrella sampling, working with many initial conformations can quickly become…

Avoid Restart Headaches: Smart Input Selection for NVT Equilibration in GROMACS Wizard

OneAngstrom

One of the most frequent pain points in molecular modeling is restarting a simulation step after modification or failure. If you’ve ever run a protocol, reached the equilibration stage, and then had to dig back through directories to track down…

When Your Molecules Start to Rock: A Simple Way to Show Local Motion in 3D

OneAngstrom

One of the recurring challenges in molecular modeling is how to effectively convey localized, subtle motions in complex molecular systems. Whether you’re preparing a presentation or a visual abstract for a paper, clearly illustrating conformational dynamics in a way that…
