For molecular modelers working with free energy calculations, computing the Potential of Mean Force (PMF) can be a challenging and often error-prone process. One of the most common bottlenecks is merging umbrella sampling results into a reliable PMF profile. Errors…

One of the recurring challenges for molecular modelers—especially those new to a platform—is getting started with complex software tools and understanding how to perform key tasks without getting overwhelmed by documentation. If you’ve ever faced a steep learning curve when…

When preparing molecular animations, one of the common challenges faced by modelers is creating smooth and accurate camera movements that highlight important molecular features without disorienting the viewer. A particularly useful animation in SAMSON is the Orbit camera, which makes…

Molecular modelers often need to visualize complex structures where clear, distinguishable visual components enhance interpretation. Whether you’re color-coding residues, chains, subunits, or datasets, using carefully designed color palettes is key. Poor palette choices can make important elements indistinguishable, especially for…

Communicating molecular structures effectively isn’t just about showing atoms and bonds — it’s about delivering clarity. For molecular modelers, one persistent challenge is depth perception: distinguishing foreground and background parts in complex 3D structures. If you’ve ever struggled with interpreting…

When presenting molecular structures or simulating molecular processes, clarity is often key. Complex molecules with hundreds—or thousands—of atoms can easily overwhelm your audience and obscure the insights you want to share. Whether you’re preparing a lecture, building an educational video,…

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…
