As a molecular modeler, you might have encountered the following situation: you’re trying to reproduce simulations from a paper, or continue a project started on another machine. But your local GROMACS version doesn’t quite match the one previously used. Differences…

If you’ve ever launched molecular simulations in the cloud—such as protein structure predictions or molecular dynamics simulations—you know that managing these jobs efficiently can quickly become a challenge. You might lose track of which simulations are running, which ones have…

Many molecular modelers spend significant time navigating menus, remembering shortcuts, and writing scripts to perform everyday tasks: visualizing surfaces, modifying representations, or selecting atom groups. While flexibility is appreciated, the friction can add up—especially when switching between modeling tools and…

Switching between different versions of GROMACS isn’t just a technical preference—it’s often a necessity for molecular modelers. Whether for ensuring reproducibility, taking advantage of specific performance improvements, or simply using a cluster’s precompiled GROMACS, being able to control the version…

One of the subtle yet recurring challenges in preparing biomolecular systems for simulations is the question of what to do with crystal waters. These water molecules, often captured in PDB structures, can be either essential to the biological function or…

Preparing molecular animations for presentations often raises the question: how can I make certain components of a model appear and then vanish in sync with narration or key visual moments? Whether you’re explaining reactive sites in a protein or walking…

One of the key challenges in molecular modeling is communicating complex molecular motions clearly. Whether you’re modeling ligand binding, protein folding, or molecular assembly, it’s often difficult to visualize trajectories in a way that’s intuitive to others — or even…

For many researchers and developers working in molecular modeling, one of the main challenges is integrating custom algorithms or tools with existing visualization and simulation environments. Often, researchers have developed their own code (for structure analysis, energy calculations, or custom…

When preparing molecular animations or presentations, it’s often important to convey structural dynamics in a clear and intuitive way. A common need is to rotate a specific part of a molecule—like a ligand, domain, or fragment—around its own center, rather…
