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 Shift a structure, and suddenly your topology is no longer valid.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…

When working with complex biomolecular structures, selecting the right atoms, residues, or fragments can feel like searching for a needle in a haystack. Scrolling through long lists or manually clicking in the Document view becomes inefficient as models grow in…
