The GENIE collaboration maintains a popular suite of software products for the experimental neutrino community. They include:

• GENIE Generator:
  The well-known GENIE Generator product implements a modern framework for Monte Carlo event generators and includes state-of-the-art physics modules. The GENIE physics model is universal and comprehensive: It handles all neutrinos and targets, and all processes relevant from MeV to PeV energy scales. The Generator includes several tools (flux drivers, detector geometry navigation drivers, and specialized event generation apps) to simulate complex experimental setups in full detail. The GENIE Generator is used by nearly all modern neutrino experiments and its predictions serve as standard reference points for the neutrino community.


• GENIE Comparisons (closed source):
  The Comparisons product includes very extensive curated archives of neutrino, charged-lepton and hadron scattering data, as well as highly-developed software to produce a comprehensive set of data/MC comparisons. It includes embedded interfaces to the Professor tuning tool which "reduces the exponentially expensive process of brute-force tuning to a scaling closer to a power law in the number of parameters and allows for massive parallelisation". The Comparisons product plays a key role in comprehensive model characterization in GENIE, it underpins the GENIE global analysis, and it enabled the production of several new tunes.


• GENIE Tuning (closed source):
  The Tuning product implements the powerfull new GENIE global analysis of neutrino scattering data. The GENIE global analysis produces physics tunes which are fully integrated in the Generator product.


• GENIE Reweight:
  The Reweight product includes a selection of tools to propagate model uncertainties and to support generator-related analysis tasks. The reweighting procedure has inherent limitations. Important modelling systematics are not reweightable in principle and they have no corresponding weight calculator in the Reweight product. Indeed, the GENIE tuning procedure itself makes no use of the Reweight product but it relies on response functions constructed from brute-force parameter scans made with the aid of the Professor tool. Currently, the Reweight product it does not provide the full systematic error for any GENIE tune. However, we have medium-term plans to overhaul this product and use it for public release of the detailed Professor/YODA response functions constructed from our brute-force systematic parameter scans, as well as to release all covariance matrices from the GENIE global fits of neutrino scattering data. The upgraded Reweight product will support all public GENIE physics tunes!


• Prof-GENIE (closed source):
  GENIE / Professor interface code.


• GENIE UnitTests:
  General support tools, unit tests etc


• GENIE AVS-CI:
  Automated Validation Suite - Continuous Integration


• GENIE Lamp:
  The "lamp" is a collection of scripts for building from scratch GENIE, including all the necessary external packages.
