When modeling molecular systems at the atomic level, selecting specific atoms based on quantitative criteria is often necessary—but rarely straightforward. Whether you need to isolate water molecules, highlight carbon atoms, or extract a structure within a geometric region, doing it…

Many molecular modelers often find themselves needing to align structures along specific axes or planes—whether it’s for preparing clean visuals, simplifying comparisons, or ensuring symmetrical arrangements for simulations. If you use SAMSON, you’ll be glad to know that aligning structures…

If you’ve worked with crystallographic protein structures, you’ve probably come across a common frustration: a PDB file only shows the asymmetric unit, not the complete biological assembly. This often leaves molecular modelers wondering how the actual protein complex is organized…

Protein-protein docking can be computationally intensive, especially when the search space is left unconstrained. If you know or suspect where a protein binding site lies, one practical way to speed up protein docking is by limiting the search domain. In…

When setting up a coarse-grained (CG) simulation with the MARTINI force field in GROMACS, many modelers run into a subtle but frustrating issue: unrealistic solvent packing that leads to simulation artifacts, often caused by solvent molecules overlapping with the solute…

One of the subtle yet persistent challenges molecular modelers face during molecular dynamics simulations is input file mismanagement—especially during equilibration steps. When performing NVT Equilibration (constant Number of particles, Volume, Temperature), even a small mistake in choosing the right input…

Creating engaging and informative animations is often a challenge in molecular modeling, especially when trying to convey 3D structures and spatial relationships clearly. One recurring issue modelers face is how to make their molecular presentations more dynamic without overwhelming the…

When working on complex molecular modeling projects, collaboration becomes not just helpful, but essential. Whether you’re co-authoring papers, sharing protein structures, or running simulations in the cloud, you need a simple and secure way to manage who sees, edits, or…
