While SAMSON is continuously updated to improve performance and add features, some users—especially in academic or enterprise settings—might need to run a previous version to ensure compatibility with specific workflows, operating systems, or legacy extensions. If you’ve ever struggled to…

Molecular modelers often work in complex research environments where consistency and reproducibility are critical. In some cases, a team or a collaborator may still rely on an earlier version of a software tool. Or perhaps an older SAMSON Extension is…

One of the recurring challenges for molecular modelers working with SMILES files is identifying and isolating molecules that contain specific substructures. Searching by substructure matters—a lot—when you’re building small molecule libraries, designing focused chemical series, or preparing datasets for further…

Working with conformational pathways and molecular dynamics trajectories often requires efficient ways to visualize movement between structures or along predefined paths. Molecular modelers frequently face this need, whether to analyze results, showcase simulations, or communicate structural changes over time. To…

Molecular modelers often face the challenge of presenting complex atomic transitions and simulations in a clear and visual way. Whether you’re showcasing conformational changes, docking processes, or molecular dynamics, it’s helpful to create a visual trail that tracks how atoms…

Ever tried to present a complex molecular system, only to find that viewers get overwhelmed by all the atoms and bonds popping up at once? A common challenge in molecular modeling is not just building great models, but communicating them…

In molecular modeling, selecting specific residues in a large biomolecule can be tedious—especially when working directly in a dense 3D structure. Whether you’re prepping a simulation or trying to highlight particular regions, pixel-perfect clicking in the 3D Viewport just isn’t…

Before running advanced analyses such as ligand unbinding pathway searches or energy minimizations, it’s critical to properly prepare your molecular models. For many molecular modelers, skipping this step—or not doing it thoroughly—leads to frustrating errors during simulation, non-physical results, or…

One of the small but often frustrating challenges in molecular modeling with GROMACS is selecting the right input structure before running NVT equilibration. 🧬 It’s a critical step, but easy to overlook—especially if you’ve lost track of your project’s flow,…
