 Using the `-o` option will result in overlays being saved for each comparison (as .mol2 files). The matrix of
 similarities is also saved as a raw numpy matrix ( _i.e._ as
 `roy_similarity_matrix.txt`), and can be read back in (with `-m`) to skip the packing-similarity analysis, if, for
 example, a different clustering algorithm is desired or part of the script has been changed.

+The `-s` option will strip all terminal atoms and carbon atom chains up to hetero atoms (e.g.
 the methyl of a methoxy will be removed), which may be useful for identifying more coarse- grained similarity that
 ignores small changes in the periphery of the molecule. A new cif is created containing the stripped molecule and
 analysis is performed using this file. Note that disordered experimental structures present in the input database will
