Running GENIE

The GENIE manual is here (PDF file). The practical examples start on page 59. Here's the first example, adapted for running at Nevis, and with an argon target. Note that the νμ histogram in this flux file is named "numu".

  Archeology: on 5-Apr-2017, I copied the flux files from uboonegpvm01.fnal.gov:/uboone/data/flux, and the GENIE spline files from https://www.hepforge.org/archive/genie/data/.

This example is straight from the manual: π+ on O, with kinetic energy 200 MeV:

As described in the GENIE manual, to turn various models on/off you need to generate new spline files. The program for doing that is gmkspl, described on page 63 of the manual. You'll want to copy the directory $GENIE/config/ to your work area, then copy and edit file EventGeneratorListAssembler.xml; that revised file will become an input list to gmkspl. An possible example (νμ on Ar, up to 10 GeV):
