A molecular model can contain many structural groups, and scanning them one by one is a slow way to answer simple questions: Which groups are unusually large? Which carry a particular formal charge? Where are the carbon-rich or oxygen-rich regions?…

When a molecular project contains many file nodes, a small targeting mistake can make it harder to find the item you meant to inspect. SAMSON’s Node Specification Language (NSL) provides a focused way to describe file nodes using attributes such…

A molecular modeling task often starts simply: adjust a structure, repeat a set of operations, inspect the result, and record what you did. The trouble begins when the same sequence has to be repeated across many structures—or revisited weeks later.…

A molecular structure can contain thousands of atoms, but a useful binding-site question is often much smaller: Which receptor residues are near the ligand? Which contacts involve polar atoms? Are nearby waters or possible clashes worth inspecting? Finding these atoms…

A small change to a molecular model can have consequences beyond the atom or molecule you meant to touch. The wrong selection can make an inspection misleading, a measurement can be hard to interpret without knowing which nodes it refers…
