A molecular modeling workflow can stall for a surprisingly ordinary reason: the tool you need is not available in your current installation, or you are unsure whether an extension will work with your operating system, SAMSON version, or plan. SAMSON…

A familiar frustration in molecular modeling: the structure in front of you looks plausible, but the binding site is too closed to inspect how a ligand might fit. A static structure captures one arrangement—not the range of motions a protein…

A familiar frustration in molecular modeling is finding a useful DNA origami design, then discovering that the file, provenance, or intended workflow is not immediately clear. A structure may be available as a design file, a component, or simulation input—and…

A molecular model can contain the information you need and still be difficult to read. A crowded structure, an unfamiliar chain layout, or a numerical property such as temperature factor may be hard to interpret when every atom has the…

Assembling a molecule in 3D can become surprisingly fiddly: atoms need plausible connections, hydrogens may need adjustment, and a fragment can overlap the structure instead of fitting into it. Building atom by atom gives you control, but it also means…

A molecular structure can look compact in one frame and open in the next. But visual inspection alone can make it difficult to tell whether a region has actually become less exposed to solvent—or whether the apparent change is just…

A molecular path can contain many frames, and a protein backbone can change gradually—or shift in a small region while the rest of the structure appears stable. Looking at structures one by one makes it difficult to keep track of…

A trajectory can be difficult to interpret when played only from its starting frame to its ending frame. You may want to revisit a transition, compare conformations in the opposite order, or simply inspect how a structure arrived at a…

A molecular scene can contain all the right structural information and still be difficult to interpret. Overlapping parts may seem to merge, the distance between objects may be unclear, and jagged edges can distract from the structure itself. Before changing…
