When working with molecular dynamics, modeling the transition pathway between two conformations—such as a ligand entering or exiting a binding pocket—is central to understanding molecular function. But here’s the catch: even when those conformations are relaxed local minima, the path…

A common challenge in molecular modeling is navigating complex macromolecular assemblies—especially when symmetry is involved. Many tools detect symmetry in biological structures, but what happens when more than one symmetry group is found? If you’re using SAMSON’s Symmetry Detection extension,…

When collaborating on molecular modeling projects, one quiet frustration for researchers is project portability—specifically, making sure nothing essential is left behind when sharing a molecular model with a colleague or switching from one computer to another. Whether you’re creating a…

After completing a protein docking calculation, molecular modelers often ask themselves: how reliable is this result? Which ligand pose should I consider most promising? How is the ligand interacting with the protein? If you’ve used the Hex Extension in SAMSON,…

If you’ve ever prepared molecular animations for presentations, publications, or teaching, you’ve probably faced a frustrating challenge: how do you control exactly when a molecule (or part of it) appears in an animation? Whether you’re explaining a reaction mechanism or…

For molecular modelers, flexibility is key. You may want to quickly switch between tools, test out new algorithms, or streamline your modeling environment. Customizing your setup can become time-consuming, especially when working with a wide array of software modules. SAMSON…

One of the most common challenges for molecular modelers is setting up and running molecular dynamics (MD) simulations efficiently—especially when using powerful tools like GROMACS. While GROMACS is a widely respected package in computational chemistry, getting it installed and optimized…

One common hurdle for molecular modelers starting with a new software platform is the installation process—especially in restricted computing environments like universities, research institutions, or shared lab machines. Needing admin rights can delay work for hours or even days. Fortunately,…

When preparing scientific animations to illustrate molecular processes, timing is everything. Whether you’re presenting a protein folding event or the binding of a ligand at an active site, getting your visuals to clearly communicate temporal changes is essential. One common…
