Scoring evaluation Decoys generation Read and calculate properties for reference compounds. File should have at least two columns: SMILES & ID Steps:1 - read all compounds from the library you want to screen 2 - calculate properties for all the compounds: MW, LogP, HBDon, HBAcc, Rotatable bonds3- calculate formal charge: not included in the fitlering process after --> to choose if we want to choose decoys with same chargeor not and include it into the filtering step filtering step:for each reference compound, compounds with similar propertiesamong the commercially available ones are selected to be usedfor fingerprint calculation and final decoys selection.Default properties and ranges:MW +/-50LogP +/- 0.5HBDon +/-1HBAcc +/-1Rotatable bonds +/-2 Fingerprints:RDkit topological fingerprints caluclated for reference and potential decoysFingerprint similarity: Tanimotorows are sorted by increasing similarity first 10 rows (10 compounds with lowest similarity) are written as decoys, one file per reference active molecule Ligand preparation Plot AUC versus "number of ligands with RMSD <2Angströms" Ability to retrieve cocrystallised binding modes The 3 metanodes below are containing this small WF in green To handle consensus ranking WARNINGWhen active compounds arereally similar, decoys selectedcan also be similar and we canend up with less than 10decoys for one activecompound. We develop thisWF to ensure that we pick 10decoys (you can change thisvalue directly in the rowsplitter) per active.
