Monte Carlo simulation must be corrected using weights to provide predictions that can be compared to data. These corrections include generator-level event weights to account for NLO (and higher) calculations as well as scaling the simulation to the recorded data integrated luminosity.
The Generator-Level Analysis handles these MC event weights as well as handling
bookkeeping of event selection cuts for each systematic variation. It can be
called using GeneratorLevelAnalysis.
To set up cut bookkeeping and generator-level analysis in your job, include the following text in your config.yaml file:
# Add the generator-level analysis block here
GeneratorLevelAnalysis: {}
Rerun your code to make sure that everything is working properly. When you are satisfied with the code changes, commit and push them.
