GNA software

By developing GNA software we are pursue the following main goals:

  • Developing a framework that enables a user to build comprehensive physical models and perform statistical analysis.
  • Implementing the analyses for the Daya Bay and JUNO experiments.
  • Implementing the global analysis of the neutrino data.

The software development is currently on the alpha stage. We plan to open the code for general public as the documentation is ready. Presumably this will happen by the end of 2018.
