Editing molecular structures interactively is often a challenge. A small change can provoke a cascade of inconsistencies, especially when bond orders, atom types or valence states must remain chemically realistic. What if your simulation tool helped you maintain chemical plausibility…

Comparing protein structures often requires more than just global alignment. In many molecular modeling projects, only a specific domain or region—such as an active site, a loop, or a conserved helix—is of interest. Aligning full proteins may obscure meaningful local…

Running a production Molecular Dynamics (MD) simulation can be both exciting and daunting, especially after spending valuable time setting up and equilibrating your system. But before pressing that Simulate button in the SAMSON GROMACS Wizard, it’s critical to double-check that…

Zooming into molecular structures is something every modeler does—whether to inspect active sites, focus a presentation on a ligand interaction, or refine an animation. But if you’ve ever been frustrated by a camera that zooms straight into a single point…

Setting up molecular dynamics simulations can be time-consuming, and one of the most common stumbling blocks is selecting the correct input structure at each simulation stage. If you’re using SAMSON’s GROMACS Wizard for your simulations, understanding how to properly link…

Working with molecular simulations often requires building systems with multiple copies of the same protein. For example, studying aggregation, self-assembly, or phase separation phenomena means that the ability to efficiently generate replicas becomes essential. If you’ve ever had to create…

When preparing scientific presentations or videos, one of the most common frustrations for molecular modelers is illustrating how components of a complex biomolecular system separate or disengage—without adding unnecessary clutter or manually repositioning dozens of atoms or structures. This is…

One of the common challenges in molecular modeling is keeping track of specific parts of a complex system during simulations or animations. For instance, you may want to closely follow an active site in a protein, or a ligand as…

One of the most common and time-consuming tasks in molecular modeling is selecting subsets of atoms and tweaking their properties. Whether you’re preparing input structures, scripting transformations, or just exploring molecular shapes, doing this atom-by-atom can quickly become inefficient and…
