class Dragon(object):
    """
    An interface to Dragon 6 and 7 chemoinformatics software.

    Parameters
    ----------
    version: int, optional (default=7)
        The version of available Dragon on the user's system. (available versions: 6 or 7)

    Weights: list, optional (default=["Mass","VdWVolume","Electronegativity","Polarizability","Ionization","I-State"])
        A list of weights to be used

    blocks: list, optional (default=False)
        A list of descriptor blocks' id. For all of them parameter SelectAll="true" is given.
        To select descriptors one by one based on descriptor names, use Script Wizard in Drgon GUI.

    external: boolean, optional (default=False)
        If True, include external variables at the end of each saved file.

    Notes
    -----
        The documentation for the rest of parameters can be found in the following links:
            - http://www.talete.mi.it/help/dragon_help/index.html
            - https://chm.kode-solutions.net/products_dragon_tutorial.php

        In the current version, we recommend the user to use this class with the following parameters:
        molInput = 'file'
        molfile = path to one SMILES representation file with .smi format or a dictionary of other formats
        script = 'new'

    Examples
    --------
        >>> from cheml.chem import Dragon
        >>> drg = Dragon(**parameters)
        >>> drg.script_wizard(script, output_directory)
        >>> drg.run()
        >>> df_path = model.data_path  # path to the output file
        >>> df = pd.read_csv(df_path, sep=None, engine='python')
        >>> df = df.drop(['No.','NAME'],axis=1)
