-=== Running gevgen_nuisance (optional alternative) ===
-
-Other than the standard gevgen application, if built against GENIE events later than GENIE 2.12.0, NUISANCE can also provide a gevgen_nuisance app, with additional features to support the creation of ‘NUISANCE-ready’ events.
-
-To build gevgen_nuisance, you will need to build with the option ‘-DBUILD_GEVGEN=ON’ during the cmake configure statement as shown in the build notes here:
-
-{{{
- $ cmake ../ -DUSE_GENIE=1 -DBUILD_GEVGEN=1 
-}}}
-
-The gevgen_nuisance can be ran in a similar way to the normal gevgen application but flux inputs and target definitions can be provided in simpler formats
-
-In our example we want to generate events for a MiniBooNE muon neutrino flux on a CH2 target. Therefore we run
-
-{{{
- $ gevgen_nuisance -n 250000 -f MiniBooNE_fhc_numu -t CH2  
-}}}
-
-We should then open the output event file to check it constrains the GENIE event tree ‘gtree’ object and the flux and event rate predictions.
-
-Notice that we no longer need to run PrepareGENIE on gevgen_nuisance events before using them nuisance. 
-
-gevgen_nuisance also provides extra support for mixed target and flux specifications. For further notes on these see:
