Grid box generation defines the three-dimensional spatial region within which the docking search algorithm will explore candidate ligand poses, centred on the identified active site and sized to fully encompass the binding pocket together with a modest surrounding margin sufficient to accommodate reasonable ligand flexibility and positional uncertainty. An excessively small grid box risks excluding legitimate binding poses that extend beyond the defined boundary, while an excessively large grid box unnecessarily increases computational search time and can reduce docking accuracy by permitting non-physiological poses outside the true binding site; grid box dimensions are therefore typically validated by confirming that a redocking calculation successfully reproduces the pose of any known co-crystallised ligand within an acceptable positional deviation.
