The Final State Analysis (FSA) package is a CMSSW analysis framework.
The package contains a complete implementatation to build a POG-approved
PAT tuple, and utilities for generating plain ROOT ntuples from the PAT tuple.
Documentation: https://github.com/uwcms/FinalStateAnalysis/wiki
Automated tests:
| 53X PAT + Ntuple |  |
| 42X PAT + Ntuple |  |
| 53X Ntuple Only |  |
Current CMSSW versions: 5_3_14.
The installation instructions are the same for both.
Get a supported CMSSW release area::
scram pro -n MyWorkingAreaName CMSSW CMSSW_VERSION
cd MyWorkingAreaName/src
# Setup your CMSSW environment
cmsenv
# Run this before doing ANYTHING else in src
git cms-initCheckout the FinalStateAnalysis repository::
git clone --recursive https://github.com/uwcms/FinalStateAnalysis.git
cd FinalStateAnalysisThis will checkout master branch with the lastest and greatest version of the code.
Use this branch for the production of PAT-tuples.
You might also want the Summer 2013 compatible branch, if so you should additionally run:
git checkout -b summer2013 origin/summer2013For development, use the 53X_SLC6_Dev branch,
git checkout -b 53X_SLC6_Dev origin/53X_SLC6_Devand then proceed as normal.
Checkout the needed CMSSW tags:
cd recipe/
# Checkout needed packages and apply patches
# This enables all options. You can turn off things you don't need.
# NB that in the hcp2012 changes the options won't do anything.
PATPROD=1 LUMI=1 LIMITS=0 ./recipe.sh
# Compile
cd ../../
# Avoid the new strict version of the compiler by relaxing some flags
export USER_CXXFLAGS="-Wno-delete-non-virtual-dtor -Wno-error=unused-but-set-variable -Wno-error=unused-variable -Wno-error=sign-compare -Wno-error=reorder"
scram b -j 8You must always set up the CMSSW environment + some extra variables from FinalStateAnalysis::
cmsenv
source $CMSSW_BASE/src/FinalStateAnalysis/environment.shFor python plotting enhancements, install the custom python virtualenv and extra packages (note this is not necessary for PAT tuple production)::
./install_python.sh
yolk -l # List installed packages
