    details, see

    and loops. Dong GQ, Fan H, Schneidman-Duhovny D, Webb B, Sali A.
    Bioinformatics. 2013

    \note This potential is independent of the orientation of the pairs of
          particles. Use OrientedSoap instead for a score that takes
          orientation into account.

    You need to use IMP::atom::add_dope_score_data() to add the requisite
    atom type data to the particles being scored.
