Table summarizes the number of compounds before and after curation and the number of fragments generated for the two NP libraries. It is noteworthy the large number of fragments generated from COCONUT (more than 2.5 million). For both NP libraries, the percentage of "Fragments RO3" is relatively small (2.5% and 1.5%, for LANPDB and COCONUT, respectively). Table summarizes the number of total fragments and "Fragments RO3" for CRAFT and the four fragment libraries of chemical vendors.
