Recipe for PAT layer 1 production

  1. Setting up the environment
  2. Preparing the CMSSW configuration file
    • copy the latest CMSSW configuration file (above) in your production directory
    • check that the output file name is generic (e.g., patLayer1.root)
    • make sure that this file "works" (if there is any error, please report) by running python <file_cfg.py>

  3. Preparing the CRAB configuration file
    • copy the attached crab.cfg file in your production directory and modify it:

    Keyword Description Example
    datasetpath the sample you [[][subscribed]] to /SUSY_LM0-sftsht/Summer08_IDEAL_V11_v1/GEN-SIM-RECO
    pset the CMSSW configuration file name (see previous step) patLayer1_fromSummer08redigi_V#_cfg.py
    storage_element the site where you will store the data (see SiteDB) T2_DE_RWTH
    publish_data_name the name of the dataset you are going to publish. Name convention: [Primary Data Set]+[CMSSW release]+"SUSYPAT"+[Tag number]+[version number] SUSY_LM0_228_SUSYPAT_V5_v1
    eMail your e-mail address, to be informed of the progress of your jobs  

  4. Running and publishing into DBS
    • once this is all setup, submit your jobs
       crab -create
       crab -submit
    
    • you will be informed by e-mail when the jobs have finished
    • once all jobs have completed, retrieve the results with crab -get
    • if everything went fine, publish with crab -publish

  5. Post-processing
    • check the data has been inserted into DBS (you can find the full dataset path from UserProcessedDataset in any of the CMSSW .stdout files):
    InspectDBS2.py --DBSURL=https://cmsdbsprod.cern.ch:8443/cms_dbs_ph_analysis_02_writer/servlet/DBSServlet --datasetPath=<full dataset path>
    
    • run over it once to check that it was correctly registered
    • put a link to the DBS entry of your published layer 1 file in the table below

  6. Trouble-shooting
  7. If something went wrong, you can revert (ALERT! with caution!):
    • delete the samples produced from disk (using lcg-del and checking the location in the CRAB .xml files)
    • remove them from DBS:
    python $CRABDIR/python/DBSDeleteData.py --DBSURL=https://cmsdbsprod.cern.ch:8443/cms_dbs_ph_analysis_02_admin/servlet/DBSServlet --datasetPath=<full dataset path, as above>
    
    • start over
