Installing an older version of a software platform can be a challenge, but sometimes it’s necessary for compatibility or workflow reasons. If you’re using SAMSON, the integrative molecular design platform, and need to revert to an older version, we’ve got…

When working with molecular models, effectively visualizing complex data is crucial. Color palettes are an essential tool in the molecular modeler’s arsenal, helping to differentiate components, highlight patterns, and effectively communicate scientific insights. But how do you simplify this often…

One common challenge faced by many molecular modelers is ensuring reproducibility and compatibility between different simulations, especially when working across teams or reproducing results from published work. Since software like GROMACS evolves rapidly, slight version mismatches can generate inconsistencies in…

Working with publicly available protein structures can feel like opening a surprise package. Sometimes, it’s all there — chain complete, atoms in place, ready for simulation. More often, though, it’s not. Missing heavy atoms, absent side chains, incomplete backbones, protonation…

If you’ve ever needed to simulate the same molecular system under multiple conformations — for example, in Umbrella Sampling or conformational ensemble simulations — then you probably know how time-consuming it can be to prepare each conformation manually. Good news:…

In molecular modeling and animation, we often focus on what moves. However, sometimes what doesn’t move is just as important. For molecular modelers who want to control which parts of a molecule are in motion and which remain static, SAMSON…

If you’re working on a scientific project that relies on a specific version of SAMSON for compatibility reasons — perhaps due to an extension that was developed for an older API, or to reproduce simulation results — reinstalling a past…
