Run the Analyzer

When running for the first time, run the setup script in order
to mount eos on lxplus, create softlinks and create/update filelists

cd BoostedRazorAnalysis/Analyzer
source scripts/setup.csh

Before running check/set the options for the Analyzer in settings.h

More info about Analyzer:

• The Analyzer program is basically an event looper, histograms/methods/cuts etc. are defined in [Name]_Analysis.h
• All settings (printed also while running) are defined in settings.h it also includes the Analysis code you want
• common methods (for all analyses/studies) are defined in common/AnalysisBase.h
• The cross-sections and total weight is taken straight from ntuple files
• Reweighting and systematics weight methods are also given in AnalysisBase
• Additionally there's an option (in settings.h) to save a skimmed TTree with same content for the selected events
• counts are saved for all common and specific analysis cuts in the order they are defined

Run your anaylsis code with

make
./Analyzer <output filename> <filelist.txt or root file(s) ... >
eg:
./Analyzer Bkg_TTJets_madgraph.root filelists/backgrounds/TTJets_madgraph.txt

There is a tcsh script to run the Analyzer and use the results to create plots all in once on part of the data (--test option)

source scripts/run_all.csh --test

Or run a full analysis on all samples (--run option) and similarly create plots in the end

source scripts/run_all.csh --run

Run systematics (first, set doSystematics = true in settings.h)
when running systematics, additionally must specify options:
systematicsFileName and numSyst (i.e. the line to read in syst file)

./Analyzer systematicsFileName=systematics/2015_12_18.txt numSyst=1   Bkg_TTJets_madgraph.root filelists/backgrounds/TTJets_madgraph.txt
./Analyzer systematicsFileName=systematics/2015_12_18.txt numSyst=2   Bkg_TTJets_madgraph.root filelists/backgrounds/TTJets_madgraph.txt
...
./Analyzer systematicsFileName=systematics/2015_12_18.txt numSyst=100 Bkg_TTJets_madgraph.root filelists/backgrounds/TTJets_madgraph.txt

You can remake the systematics file with:

python scripts/write_syst.py <nline>
