A new force-field workflow can be deceptively easy to start—and surprisingly easy to misconfigure. The system may be assigned to the wrong application domain, a molecular charge may not match the intended state, or the first energy readout may appear…

A color map can make a molecular model easier to interpret—or quietly make it harder. A common frustration is choosing colors that look appealing but do not help readers distinguish structural groups, follow a numerical range, or spot values that…

A molecular trajectory can produce many useful measurements: distances, energy values, RMSD, radius of gyration, and solvent-accessible surface area, to name a few. The difficulty is that looking at each measurement separately may hide how they relate. Does a distance…

Preparing a molecular-dynamics run is already a sequence of decisions. Repeating those decisions by hand for dozens of starting conformations—or for several related systems—adds effort and makes it easier to apply settings inconsistently. Batch preparation in SAMSON’s GROMACS Wizard helps…

A protein structure file may show only part of the arrangement you want to study. You open the structure, see a single chain or a small group of chains, and wonder: where are the other copies that make up the…

Protein structures are often available as snapshots: one file for a closed conformation, another for an open one. But when you are trying to understand a conformational change, two endpoints leave an important question unanswered: what might the movement between…

A molecular path can contain many frames, but a long trajectory is hard to interpret by looking at structures one at a time. A useful first question is often simpler: which combinations of two observables occur most often along the…

A molecular model can contain the answer to a scientific question and still be difficult to present. A static view may leave an audience unsure where to look, what changes, or how one part relates to another. Meanwhile, adding motion…
