A simulation box can look comfortably large and still create a problem: periodic boundary conditions make copies of the system repeat in every direction. If the solute gets too close to one of those copies, it may interact with its…

A molecular dynamics setup can be close to what you need and still require one important change: perhaps you are continuing a validated workflow, or a parameter is not exposed among the settings you usually adjust. The tricky part is…

A crystal model can look structurally convincing and still miss an important detail: some sites are not occupied in every unit cell. In a CIF file, occupancy information can describe vacancies or substitutions. If that information is overlooked, a model…

A molecular structure can contain the information you need and still be difficult to read. When every chain looks alike, or a color gradient has no clear meaning, it becomes harder to inspect a model and harder to explain what…

A molecular model can contain all the information you need and still be hard to explain. A static view may not show how components fit together, which atoms matter, or where the viewer should look. Adding motion can help—but a…

A cloud calculation can solve one problem and create another: once it has been launched, where do you check its progress, find its files, or share the result? For molecular modelers moving between structure prediction and molecular dynamics, keeping those…

A molecular dynamics run can be ready to launch and still leave you wondering: has the system actually reached its target temperature? A temperature trace that moves up and down is not automatically a problem—small fluctuations are normal—but continuing too…
