If you work in molecular modeling, you’ve likely faced the challenge of simulating multiple states or conformations of the same molecular system. Maybe you generated a trajectory from a docking animation, or you explored conformational changes using normal mode analysis.…

Potential of Mean Force (PMF) calculations are a central tool in molecular dynamics for exploring the energetics along a reaction coordinate, such as ligand binding pathways, ion transport, or conformational changes. But as any molecular modeler knows, getting a reliable…

If you’re designing or analyzing molecular systems regularly, you’ve likely spent more time than you’d like adjusting atom sizes, tweaking colors, choosing rendering styles, and setting up views to get a clear and informative visualization. This overhead can be a…

When you’re creating molecular animations, clarity matters. Whether you’re preparing a molecular movie for a publication, a presentation, or a classroom, controlling exactly when elements appear or disappear can make the difference between an obscure or a crystal-clear explanation. Enter…

When preparing molecular systems for simulations with GROMACS, one often underappreciated step is defining custom index groups. These groups play a crucial role in advanced simulations such as umbrella sampling, free energy calculations, or restrained simulations, where specific atom sets…

Visualizing complex molecular models often involves toggling visibility—switching parts on and off to focus attention or guide a viewer through a process. But a sudden change from invisible to visible can break immersion in animations or video presentations. This is…

When preparing molecular animations in SAMSON, one of the common challenges is managing the visibility of complex molecular structures throughout the timeline. For example, you may want to emphasize a particular molecular subunit by momentarily hiding others, or gradually simplify…

If you’ve been trying to generate smooth transitions between protein conformations using interpolation tools and keep running into frustrating errors like: “Cannot proceed because the structure does not make one connected component,” you are not alone. This issue is a…
