A new molecular modeling platform can be installed successfully and still leave you wondering what to do next: where to launch it, whether your computer meets the requirements, or how to get from an empty workspace to a useful molecular…

A molecular structure can be easy to inspect in 3D and still be difficult to navigate residue by residue. When you need to locate a particular part of a protein, the sequence gives you a readable map—but switching back and…

Building a small set of related molecules can become surprisingly tedious. You may have a scaffold you want to preserve, a region you want to vary, and a list of candidate replacements—but manually editing every SMILES string is easy to…

Starting a molecular dynamics simulation can feel like a collection of disconnected tasks: prepare a structure, choose a box, add solvent, minimize, equilibrate, and finally run production dynamics. The difficult part is often not any single step—it is knowing what…

Starting a molecular dynamics simulation can feel like a collection of disconnected tasks: prepare a structure, choose a model, add solvent and ions, relax the system, and finally run the simulation. The difficult part is often not any one step—it…

Placing lipids around a protein is a geometry problem before it becomes a simulation problem. The protein needs a consistent orientation, the lipid molecules need a useful orientation of their own, and the box must be sized and positioned so…

Finding the right atoms or residues can interrupt an otherwise straightforward modeling task. You may know what you want—such as lysines in one chain or side chains near a ligand—but translating that idea into a precise selection takes time. In…

A molecular animation can be scientifically clear and still be difficult to watch if the camera drifts away from the feature you want people to follow. Reframing between shots may help, but during an animation the camera’s position and its…

When a molecular modeling task stalls, the problem is not always the structure. Sometimes the challenge is finding the right tool—or realizing that a different interaction tool is currently active. SAMSON editors respond to user input, such as mouse and…
