PLATON offers two options to detect and analyse solvent accessible voids in a crystal structure. SOLV is a faster version of VOID. VOID is useful when, in addition to the detection of solvent areas, a packing coefficient (Kitaigorodski) is to be calculated. The SOLV option is used as part of a SQUEEZE calculation. Some background information may be obtained from the paper Acta Cryst (1990) A46, 194-201.
