Installing GROMACS for molecular modeling and simulation has traditionally been a technical barrier for many researchers and students. It often involves downloading source code, managing dependencies, ensuring compatibility with specific compilers, and sometimes taking deep dives into system-level settings. If…

If you’ve ever loaded a PDB file into your molecular modeling environment only to find a lone asymmetric unit floating in empty space, you’re not alone. Most PDB files describe just the minimal repeating unit of a biological assembly or…

When working on complex molecular systems, the ability to quickly select relevant atoms, residues, or molecules is vital. Whether you’re visualizing a protein-ligand interaction, preparing a simulation, or analyzing channels through a membrane, making precise selections can save time and…

Molecular simulations often rely on enhanced sampling techniques to capture rare events or transitions. One such method is Umbrella Sampling, widely used to estimate free energy profiles along reaction coordinates. However, a common challenge many molecular modelers face is determining…

When building animations in molecular modeling, a common challenge is highlighting which atoms or residues are appearing, disappearing, or changing over time. For presentations, educational videos, or simple visualization clarity, we often need a way to guide the viewer’s focus…

Have you ever had a long list of SMILES strings and wished there were an easy, visual way to convert them into 3D structures? Whether you’re building a virtual screening library, exploring molecular properties, or just trying to visualize molecules…

When analyzing molecular structures, it’s common to quickly measure a distance or an angle and move on. But what happens when you need to revisit those measurements later? If you’re using temporary measurements in SAMSON, there’s a high chance you’re…
