DATA & FILE OVERVIEW
---------------------

1. File List

   A. Filename: README.txt      
      Short description: readme file       

   B. Filename: ZINC20_smiles.tar.gz    
      Short description: archive with 100 SMILES files (10 million molecules each) encompassing all the ZINC20 molecules available
 in early March 2021. Stereochemistry has been expanded where necessary. Names of molecules follow the format ZINCID_index, 
where index is related to a specific stereoisomer. Dominant tautomer and protonation state at pH 7.4 is already provided
   B1. smiles/ directory containing the above file in 20 easy-to-download chunks

   C. Filename: ZINC20_fingerprints.tar.gz    
      Short description: archive with 100 Morgan fingerprint (radius 2, 1024 bits) files (10 million molecules each) 
encompassing all the ZINC20 molecules. Format is appropriate for Deep Docking (comma-separated list of indexes of set bits)
   C1. fingerprints/  directory containing the above file in 20 easy-to-download chunks

   E. Filename: smiles_count.txt   
      Short description: file listing per-file and total number of SMILES

   F. Filename: fingerprints_count.txt   
      Short description: file listing per-file and total number of Morgan fingerprints

METHODOLOGICAL INFORMATION
---------------------------

1. Description of methods used for collection/generation of data: 
* SMILES were prepared using Openeye flipper (https://docs.eyesopen.com/applications/omega/flipper.html) and 
* QUACPAC (https://www.eyesopen.com/quacpac) tools. 
* Morgan fingerprints were then generated with rdkit (https://www.rdkit.org/docs/index.html) and 
translated into Deep Docking format, using the 
* compute_morgan_fp.sh script from https://github.com/jamesgleave/DD_protocol/tree/main/utilities
