SpartyJet is a set of software tools for jet finding and analysis, built around the FastJet library of jet algorithms. SpartyJet provides four key extensions to FastJet: a simple Python interface to most FastJet features, a powerful framework for building up modular analyses, extensive input file handling capabilities, and a graphical browser for viewing analysis output and creating new on-the-fly analyses. Many of these capabilities rely on a ROOT-based backend. Beyond finding jets, many jet tools in SpartyJet perform measurement of jet or event variables, available to subsequent tools and stored in the final output.

Example: Boost 2011

The BOOST 2011 report incorporated a series of substructure comparisons, using FastJet-based tools implemented in SpartyJet. These tools stand alone and can be downloaded (for now) from the SpartyJet SVN browser; they're in the trunk/ExternalTools directory. The scripts used to define the BOOST analyses, scan input and output parameters, and make the comparison plots, can be found here.
