| # Script to generate root file with a histogram containing | ||
| # the simulated number of background events for a given number of toys | ||
| ############## | ||
| # Usage: First run Higgs Combine tool, for example: | ||
| # combine datacard.txt -S 0 -M GenerateOnly -t 10000 --saveToys | ||
| # | ||
| # The -M GenerateOnly option generates only toys without running the limits. | ||
| # Greatly decreases the processing time: for a single-bin counting experiment, | ||
| # can generate 10K toys in ~1 min | ||
| # | ||
| # Can use the --toysFreqentist to generate frequentist toys. See: | ||
| # https://hypernews.cern.ch/HyperNews/CMS/get/higgs-combination/572/1/2/1/1/1.html | ||
| # | ||

| # Usage: python parseCombine.py name_of_output_root_file_from_combine_command ntoys | ||
