%description
Methods to compute chemical similarity between two or more reactions and
molecules. Allows masking of chemical substructures for weighted
similarity computations. Uses packages 'rCDK' and 'fingerprint' for
cheminformatics functionality. Methods for reaction similarity and
sub-structure masking are as described in: Giri et al. (2015)
<doi:10.1093/bioinformatics/btv416>.
