genie-reader

The goal of this project is to convert Monte-Carlo simulation from GENIE to IceTray format without interfering with GENIE classes. Two IceTray modules and segment which combines them are available.

The project relays on GENIE generic command-line tools. Because it is only possible to use them with a single-point geometry, interaction positions and primary neutrino directions are sampled in the cylindric volume, aligned with the new neutrino direction.

Example step1 production scripts are provided in resources/scripts/. These scripts are based on oscNext step1 scripts and should produce equivalent output.
