Fig. 4From: Comparative analyses of structural features and scaffold diversity for purchasable compound librariesThe scaled distributions of molecular weight for nine types of fragments found in the 12 datasets. Here, b represents bridge assemblies, c represents chain assemblies, Level_0, Level_1 and Level_2 represent Level 0, Level 1 and Level 2 of the Scaffold Tree, respectively, m represents Murcko frameworks, r represents rings, ra represents ring assemblies, and RECAP represents RECAP fragmentsBack to article page
