When working on complex molecular structures, it’s easy to feel overwhelmed by the number of properties associated with each atom. Whether you’re adjusting atom positions during molecular modeling or inspecting attributes to verify structural consistency, sifting through all the information…

Working on large or complex molecular systems often involves switching between several regions of interest — ligands, receptors, water molecules, cofactors, etc. Repeating selection steps every time can quickly become tedious and error-prone. Quick Groups in SAMSON address this pain…

One of the common challenges for molecular modelers is understanding how molecular components move during simulations. Whether you’re tracking a ligand unbinding from its binding pocket or studying large conformational transitions in proteins, getting a clear view of motion across…

When building or editing molecular systems, small tweaks often lead to unexpected results. Move an atom, and you might accidentally break a bond. Shift a structure, and suddenly your topology is no longer valid. This is especially painful when iteratively…

If you work with protein structures from the Protein Data Bank (PDB), you’ve likely encountered files that only include the asymmetric unit of a biological assembly. While useful, that limited view hides the full structural context proteins adopt in crystals…

When preparing molecular animations, timing is everything. If you’re showing a protein interaction, reaction mechanism, or structural transition, you often want specific molecules or components to become visible at just the right moment. Many molecular modelers struggle with objects either…

One of the recurring challenges in computational structural biology is understanding and predicting how biomolecules open or close around functional sites, such as ligand-binding pockets. Experimental structures often show only a few static snapshots—yet the biological activity is tightly linked…
