Understanding complex biomolecular structures often involves navigating dense 3D environments filled with atoms, ribbons, and other intricate representations. But even with the most accurate geometry, sometimes something just “feels off” — flat visuals that make it difficult to distinguish between…

When working with complex molecular models, even simple tasks like finding and editing a property of a specific atom can become overwhelming. If you’ve ever spent too much time scrolling through long lists of atomic attributes or lost track of…

For many molecular modelers, switching between apps, editors, and panels slows down their workflow. While SAMSON provides a rich and modular interface, not everyone realizes just how customizable it is. If you ever thought, “I wish this panel were over…

When working with molecular dynamics simulations in GROMACS, one common challenge is defining atomic groups for analysis, restraints, or pull codes. By default, GROMACS generates some standard index groups (like Protein, Water, or Ion) automatically. But what if you need…

When running simulations with the Universal Force Field (UFF) in SAMSON, molecular modelers often seek the flexibility to fine-tune atom types, bond orders, or valences. While UFF does a good job at automatically perceiving this information, there are cases—especially when…

Many molecular modelers have shared the same frustrating experience: measuring a distance or angle between atoms in a molecular system, only to realize that the value disappeared moments later. What’s going on here? In SAMSON, molecular measurements like bond lengths,…

When preparing molecular dynamics simulations that involve center-of-mass (COM) pulling — such as separating chains in a protein complex — one of the most common sources of error is the incorrect definition of the simulation box. The consequences? Unexpected interactions…
