Here we present some instructions to do =FullSim= using =CRAB=.

First, in order to use the grid and initialize the =CRAB= we need to do the following:

   * At =lxplus= (for example using CMSSW_5_1_3):
<verbatim>
source /afs/cern.ch/cms/LCG/LCG-2/UI/cms_ui_env.csh
cd CMSSW_5_1_3/src/
cmsenv
source /afs/cern.ch/cms/ccs/wm/scripts/Crab/crab.csh
</verbatim>

   * At =access= : copy the scripts (=setupgrid.sh= and =setupcrab.sh=) from Thiago's area =/home/trtomei/bin/= and do:
<verbatim>
./setupgrid.sh 
cd CMSSW_5_1_3/src
cmsenv
./setupcrab.sh 
</verbatim>

We divide the =FullSim= in three steps:

   * Step 0: Generating events and doing detector simulation using GEANT4
 
Using =cmsDriver.py= we create a config. file:
<verbatim>
cmsDriver.py Configuration/Generator/python/Zprime_to_WW_8TeV_pythia8_cff.py --step GEN,SIM --beamspot Realistic8TeVCollision --conditions START50_V13::All --pileup NoPileUp --datamix NODATAMIXER --eventcontent RAWSIM --datatier GEN-SIM --no_exec
</verbatim>

And we use the resulting configuration file ([[/twiki/bin/viewfile/Main/AnalysisOpenSpace?rev=1;filename=Zprime_M1500GeV_to_WW_8TeV_pythia8_cff_py_GEN_SIM.py.txt][Zprime_M1500GeV_to_WW_8TeV_pythia8_cff_py_GEN_SIM.py.txt]]) to create and submit jobs with =CRAB=. For this we use a crab config. file, for example ([[/twiki/bin/viewfile/Main/AnalysisOpenSpace?rev=1;filename=crab02.cfg][crab02.cfg]]).

To create and submit the jobs we use:
<verbatim>
crab -create -c task
crab -submit -c task
</verbatim>

And when the jobs are terminated we use =crab -getoutput -c task= to retrieve the output of all jobs submitted. After this we can publish the results stored in the SE, using =crab -publish -c task=.

Obs.:
user data will be published as
<verbatim>
/<primarydataset>/<yourHyperNewsusername>-<publish_data_name>-<PSETHASH>/USER
</verbatim>

where =publish_data_name= is the name you provide in =crab.cfg= and =primarydataset= is the primary dataset of the dataset you are reading (the first part of the =datasetpath= in =crab.cfg=). If you are running with =datasetpath=None= then the =primarydataset= is set equal to =publish_data_name=.
<verbatim>
/<publish_data_name>/<yourHyperNewsusername>-<publish_data_name>-<PSETHASH>/USER
</verbatim>

   * Step 1: REDIGI

With the Step 0 results published we use these as input for the second step. This step is called REDIGI and we use a newer version of CMSSW to perform this (for example, 5_2_5). First, we create a config. file using =cmsDriver.py=:
<verbatim>
cmsDriver.py REDIGI --step DIGI,L1,DIGI2RAW,HLT:5E33v4 --conditions START52_V9::All --pileup 2012_Startup_50ns_PoissonOOTPU --datamix NODATAMIXER --eventcontent RAWSIM --datatier GEN-SIM-RAW --no_exec
</verbatim>

This will create a config. file, for example ([[/twiki/bin/viewfile/Main/AnalysisOpenSpace?rev=1;filename=Zprime_M1500GeV_to_WW_8TeV_pythia8_cff_py_GEN_SIM_REDIGI_DIGI_L1_DIGI2RAW_HLT_PU.py.txt][Zprime_M1500GeV_to_WW_8TeV_pythia8_cff_py_GEN_SIM_REDIGI_DIGI_L1_DIGI2RAW_HLT_PU.py.txt]]). Using a crab config. file like ([[/twiki/bin/viewfile/Main/AnalysisOpenSpace?rev=1;filename=crab03.cfg][crab03.cfg]]) we create, submit and publish the results.

Obs.:
This step uses some =MinBias= samples. So, if SPRACE doesn't have these samples, the jobs will fail trying to open!!! 

Obs.:
To publish in this step we need to use =crab -publishNoInp= instead of =crab -publish=, because CRAB doesn't know to migrate the =MinBias= dataset used for the pileup. See the HN: https://hypernews.cern.ch/HyperNews/CMS/get/crabFeedback/6000.html

   * Step 2: RECO

Use as input the datasets published in Step 1. Create a config. file using =cmsDriver.py=: 

<verbatim>
cmsDriver.py STEP2 --step RAW2DIGI,L1Reco,RECO --conditions START52_V9::All --pileup 2012_Startup_50ns_PoissonOOTPU --datamix NODATAMIXER --eventcontent AODSIM --datatier AODSIM --no_exec
</verbatim>

Create, submit and publish the results.
