When preparing protein structures for simulation or modeling, one frequent challenge is identifying residues that adopt energetically unfavorable conformations. Even a few outliers in backbone dihedral angles can introduce strain, reduce model quality, or degrade simulation stability. That’s where the…

When studying molecular mechanisms such as ligand unbinding, full atomic trajectories are often unnecessary. Many molecular modelers prefer to focus only on a specific subset of atoms—like a ligand or a binding site—when running free energy calculations, visualizing reaction coordinates,…

Designing compelling molecular animations often becomes a bottleneck in structural biology and molecular modeling—especially when trying to clearly present docking events or compare bound and unbound states. In many cases, modelers want to show how ligands or components fit with…

In molecular modeling, every action—like building a molecule, tweaking a conformation, or applying a force field—can dramatically change your model. This flexibility is essential, but it comes with a risk: a misclick or unwanted operation may send your system into…

When setting up coarse-grained (CG) molecular dynamics simulations, solvation may seem like a straightforward checkbox. However, if you’re using the MARTINI v.3.0.0 force field with coarse-grained beads and GROMACS, there’s a subtle — but impactful — parameter you should not…

Anyone who works with molecular modeling software knows this feeling: you just adjusted a conformation, or deleted a node, or modified a complex interaction… and instantly wish you hadn’t. Modeling mistakes happen to everyone — sometimes it’s a misclick, sometimes…

Real-world crystals are rarely perfect. Defects and substitutions play a fundamental role in determining the physical properties of materials, whether it’s the hardness of a gemstone or the conductivity of a semiconductor. But for molecular modelers, simulating these imperfections accurately…

When showcasing molecular systems—whether for teaching, publications, or collaboration—communicating clearly is essential. One often-overlooked challenge is ensuring your audience knows where to look. Complex molecules or large assemblies can be visually overwhelming, especially when everything appears at once. This is…

When modeling complex molecular structures, you often need to make small adjustments to multiple atoms at once. Whether it’s repositioning a selection as a group, editing element types, or filtering through many atomic properties, doing this efficiently can save valuable…
