Pseudo Experiments HowTo

Where to find pseudo experiment results and scripts

Copy files from castor

# set the environment in order to use the CMST3 disk pool correctly
export STAGE_HOST=castorcms
export STAGE_SVCCLASS=cmst3
# do the actual copying
./copyFromCastor.py sourcedir targetdir

It is suposed to download 10 files at a time. I don't know if it really works, it's still rather slow.

Environment

When I last checked, things did not work in the plain CMSSW environment. You probably need root 5.28 (test it if you want to be sure). Therefore:

• On lxplus:
  • set the CMSSW environment
  • soure MLFit/workdir/FitMacros/WJetsMuon_New/setup.sh
• On your laptop
  • make sure root 5.28 is installed and the environment is correct

Simple analysis

python ToyAnalysis.py Directory/With/Toyres  OutputFile.root

What it does:

• there is a variable 'parameters'. for each of the parameters in this list a canvas is created with
  • the distribution of the estimated value of the parameter
  • the distribution of the estimated error of the parameter
  • the pull for this parameter

Edit this list by hand if you want other parameters. At this moment all relevant parameters for the 2 jet bin are included.

Todo's

• avoid the editing by hand of 'parameters' (can easily be solved by taking njetmin and njetmin from command line options)
• the pull distribution should be fit with a gaussian
• graphics should not pop up during running
• write a text file sumarizing the pulls for each parameter
