    Data Set Information:

    This dataset contains manually-curated experimental bioconcentration factor (BCF) for 1058 molecules (continuous values). Each row contains a molecule, identified by a CAS number, a name (if available), and a SMILES string. Additionally, the KOW (experimental or predicted) is reported. In this database, you will also find Extended Connectivity Fingerprints (binary vectors of 1024 bits), to be used as independent variables to predict the BCF. You can find additional information in the referenced papers.
    In case you had questions, please do not hesitate to contact us!


    Attribute Information:

    The provided zip file contains two files.

    (I) The file 'QSAR BCF KOW' contains the following attributes:
    1. CAS number (molecule identifier)
    2. Molecule Name (if not available, marked as 'n.a.')
    3. SMILES string to identify the 2D molecular structure
    4. LogKOW: octanol water partitioning coefficient (experimental or predicted, as indicated by the column 'KOW Type'
    5. KOW Type: indicates whether the logKOW value is experimental or predicted
    6. Experimental logBCF (quantitative response): experimental fish bioconcentration factor (logarithm form)

    (II) The file 'ECFP_1024_m0-2_b2_c.txt' contains the following molecular descriptors (to be used to predict the BCF):
    - Extended Connectivity Fingerprints (ECFPs): binary descriptors useful to predict the experimental logBCF (computed with Dragon7, default settings --> details specified in the file)
    Each row corresponds to one molecule, as identified by the SMILES field. The molecules are in the same order as in the previous file.
