You may find them useful if you work with ChEMBL data using FTP downloads and API. 1. FPS format support. Many users download our SDF file containing all ChEMBL structures in order to compute fingerprints as an immediate next step. We decided to help them and publish precomputed fingerprints in a FPS text fingerprint format . The FPS format was developed by Andrew Dalke to "define and promote common file formats for storing and exchanging cheminformatics fingerprint data sets".
