How to run on data with crab

Setting up the environment

• Check out some recent CMSSW version
• Setup the CRAB environment. Using c-shell, this means

 source /source /swshare/CRAB/CRAB_2_7_3/crab.csh 

• Check out the modules from CVS and compile
  • Note, using CMSSW version before 3.8.0, you have to additionally checkout the package 'RecoVertex/KinematicFitPrimitives'

 cvs co AnalysisDataFormats/HeavyFlavorObjects HeavyFlavorAnalysis/Bs2MuMu
 cd AnalysisDataFormats/HeavyFlavorObjects; make -j4; cd -
 scramv1 b -j4
 cd HeavyFlavorAnalysis/Bs2MuMu/test/test-data

Creating the CRAB config files

• Get the latest json file from the Onia2MuMu. For instance

 curl 'http://cmssw.cvs.cern.ch/cgi-bin/cmssw.cgi/CMSSW/HeavyFlavorAnalysis/Onia2MuMu/certification/7TeV/Collisions10/StreamExpress/Cert_132440-143336_7TeV_StreamExpress_Collisions10_JSON_BPAG_v2.txt?revision=1.1' > jsonfile 

• In the template you want to use (e.g. crab-mu-v4-XXX.cfg), modify the output storage element location. That is the lines
  • be sure to output to CSCS in case you are running on the grid

 
storage_element = storage01.lcg.cscs.ch
storage_path = /srm/managerv2?SFN=/pnfs/lcg.cscs.ch/cms/trivcat/store/user/naegelic
user_remote_dir = /data/mu-v4/XXX
