Why Running GROMACS on the Cloud Can Save You Time and Headaches

If you’ve ever tried to simulate a large molecular system using GROMACS, you’ve probably run into limitations on your local machine. RAM usage, simulation time, or even GPU availability can quickly become bottlenecks. Fortunately, the GROMACS Wizard extension in SAMSON…

Keeping Everything Together: Embedding Files and Folders in Molecular Documents

OneAngstrom

When working on complex molecular modeling projects, keeping all your related files—scripts, datasets, and supplementary materials—organized and in the right place can be a challenge. Molecular modelers often juggle structural data, downloadable database entries, computational scripts, and even research papers…

One Workflow, Many Molecules: Streamlining Batch Molecular Dynamics with SAMSON

OneAngstrom

Running molecular dynamics (MD) simulations across multiple systems can be one of the most time-consuming bottlenecks in molecular modeling. If you’ve ever found yourself repeating the same preparation and simulation steps manually for dozens of protein-ligand systems, you likely know…

Struggling to Align Molecular Structures? Here’s a Simple Way to Do It in SAMSON

OneAngstrom

Many molecular modelers know the frustration: you load a ligand or protein into your modeling environment and need to align it properly in 3D space—maybe for comparison, maybe for analysis, or maybe just to organize a complex scene. But trying…

Tidy Up Your Molecular Workspace with Node Group Selection Flags

OneAngstrom

When working with complex molecular systems, it doesn’t take long before your document in SAMSON fills with an overwhelming number of nodes—atoms, molecules, groups of molecules, visual models, annotations. Organizing and selecting them effectively can quickly become a challenge, especially…

Minimizing Only a Part of a Molecule in SAMSON: A Better Way to Adjust Structures

OneAngstrom

A common challenge in molecular modeling is the need to make small, precise changes to a structure without affecting the overall geometry. Whether you’re adjusting a functional group, refining a ligand conformation, or modifying only part of a large system,…

Loading Custom GROMACS Parameters Without the Guesswork

OneAngstrom

Researchers working with molecular dynamics simulations often need to rely on specific configuration files to fine-tune the behavior of simulation engines like GROMACS. Among these configurations, the .mdp file (Molecular Dynamics Parameters file) plays a central role. However, editing or…

Don’t Ignore Defects: Modeling Realistic Crystals in SAMSON

OneAngstrom

Most molecular modeling begins with the ideal. Perfect lattices, flawless symmetry, and pristine atomic arrangements. But real-world materials are rarely so tidy. Defects — like vacancies, substitutions, and distortions — play a crucial role in defining the physical and chemical…

A Simple Way to Add Breathing Room to Molecular Animations

OneAngstrom

When presenting complex molecular systems, timing matters. Animations that move too quickly from one state to another can overwhelm viewers, especially when trying to highlight an important molecular interaction or structural change. If you’re creating a molecular animation in SAMSON…

Simulating Many Protein Structures in One Go

OneAngstrom

Running molecular dynamics simulations across a large number of protein structures—whether they are variants, mutants, or alternative binding poses—can quickly become overwhelming. Repeating the same MD preparation steps for each conformation or each structure wastes time, increases chances of human…
