TruthToRecAssociators:

This tool(currently for HiggsToGamGam-00-00-28-08), migrated form the EvnetViewPerformance package, can do the matching between the truth and the reconstructed specific particles, according to the cuts set for the truth and reconstructed objects. Add a line(if there is no such a line) in HiggsToGamGamTruth_jobOptions.py before truthEVlooper was dumped into ntuple:

truthEVLooper += TruthToRecAssociators("Associator","defaultEventView",True)

Running the HiggsToGamGamAOD_topOptions (how to run?), then in root, type the following command:

.L effmatrix_CPh.C++

effmatrix("higgs1206",false/true)

You will got the eff-misid plots if you set the last argument to be true.
