When setting up a molecular simulation, small things can save hours down the line. One of those things is organizing your system with custom index groups. GROMACS automatically generates standard index groups like Protein, SOL, and IONS based on the…

Creating effective molecular presentations often requires more than static views. Animations can significantly improve the clarity and engagement of your visualizations. One common requirement researchers face is showcasing a protein, material, or interaction site from multiple angles without overwhelming the…

One of the most common frustrations that new users face when starting with molecular modeling platforms is the sheer complexity of tools and workflows. Even with excellent documentation, the transition from reading about a feature to applying it on your…

Working with complex molecular systems often means working with complex visuals. In tools like SAMSON, being able to direct attention to a specific region of your model can make a real difference—whether it’s for analysis, teaching, or presentation. One of…

You’re preparing a molecular model and carefully added a set of labels to atoms, residues, or molecules — only to find that they seem to vanish as you zoom out or pan across your system in SAMSON. If this sounds…

In collaborative scientific environments — from academic labs to cross-institutional research teams — sharing models, simulations, and analysis workflows is critical. If you’re a molecular modeler using SAMSON, you might have faced challenges when organizing joint work: How do you…

If you use GROMACS for molecular dynamics simulations, you’ve likely encountered the concept of index groups. While GROMACS automatically generates standard groups (like Protein, Solvent, etc.), custom index groups are essential when you need fine control during analysis or for…

One of the most overlooked steps in molecular docking workflows is the proper preparation and minimization of ligands. While skipping this step might seem tempting—especially when working with large ligand libraries—it can significantly affect docking results, particularly when ligands are…
