Dear all, there is a bug in this line: https://github.com/cms-sw/cmssw/blob/master/PhysicsTools/NanoAOD/plugins/GenWeightsTableProducer.cc#L438 double w0 = weights.at(1); The number of elements in GEN weight vector needs to be checked first. There can be events with single-entry weight vector, see e.g. these requests [1]. Cheers, Alexander. [1] https://its.cern.ch/jira/browse/CMSCOMPPR-16642#add-comment
