Unicity is defined as the proportion of molecules (or scaffolds / frameworks) that are exclusive to a given provider, i.e. that cannot be found in any other provider. The proportion of scaffolds / frameworks are expressed as the number of molecules divided by the number of scaffolds / frameworks associated with a given provider. The minimum, maximum and average values through all vendors are given in this table. The number of vendors having one of these indices up to a given threshold is given in the second part of the table.
