Custom GROMACS Index Groups Without the Guesswork

Creating custom index groups in GROMACS can be a useful—and at times necessary—part of your molecular simulation workflow. Whether you’re running umbrella sampling, tracking interactions, or preparing for free energy calculations, identifying just the right atoms or residues can save…

Pausing Molecular Animations Without Breaking the Flow

When presenting molecular animations, timing is often just as important as content. Whether you’re building a video presentation for a conference, teaching molecular dynamics in a classroom, or showcasing your latest protein-ligand interaction, being able to emphasize key moments can…

Making smarter selections with node group attributes in SAMSON

For molecular modelers working with large systems—be it proteins, materials, or supramolecular complexes—managing selections efficiently can significantly improve productivity and reduce errors. In SAMSON, the Node Specification Language (NSL) introduces a powerful way to target specific parts of your model…

Feeling Lost in Molecular Modeling Software? Try Learning by Doing

Many molecular modelers, whether beginners or experienced researchers switching to new tools, face a common challenge: getting started quickly and effectively. Dense documentation, unfamiliar interfaces, and unclear workflows often delay productivity and increase frustration. If this rings a bell, you’re…
