The Samples

The Summer '08 Production and Winter '09 Production pages say that there should be the following numbers of events for the different samples:
  • Signal
    • ??? GM1g...
  • Photon + Jet
    • 4M Pythia 6 (Summer 08)
    • 500k Pythia 8 (Summer 08)
    • 4M Madgraph (Summer 08?)
    • 25M Madgraph (Winter 09 Fast Sim)

Hints and Tips

  • To switch to a csh shell, simply type csh at the prompt. Easy, eh?
  • Changing CRAB server: In the create_XXXX.csh script, comment out the crab -create and crab -submit commands at the end, and run the steercfg.csh script. Go into the build directory (whatever you named it in steercfg.csh) and change the server crab.cfg file to your new server (e.g. legnaro). Then type crab -create and crab -submit to create and submit your jobs to the new server.
  • Black/whitelisting sites: See here for the parameters to put into the crab.cfg file.
  • Copying from a GRID site: Use, for example
> source /afs/
> lcg-cp -b -D srmv2 srm://\?SFN=/pnfs/ /data/tom/susysamples/fall08/GM1g/PATLayer1_V3/.
  • Looking at directory contents
> lcg-ls srm:// # Aachen
> lcg-ls -b -D srmv2 srm://\?SFN=/pnfs/ # Aachem proper
> lcg-ls -b -D srmv2 srm://\?SFN=/pnfs/ # Imperial
> lcg-ls -b -D srmv2 srm://\?SFN=/pnfs/ # Wisconsin
> lcg-ls -b -D srmv2 srm://\?SFN=/pnfs/ # Estonia
> lcg-ls -b -D srmv2 srm://\?SFN=/pnfs/cms/ #FNAL (T3???)
> lcg-ls -b -D srmv2 srm://\?SFN=/pnfs/ # FNAL (main???)
> lcg-ls -b -D srmv2 srm:// # Vienna
> lcg-ls -b -D srmv2 srm://\?SFN=/pnfs/ # list V4 GM1g signal samples

> # Slightly different method...?

  • Local production
> # Copy the PAT_Layer1 V4 file across
> csh
> cd /data/tom/susysamples/fall08/GM1g/PATLayer1_V4/
> source /afs/
> lcg-ls -b -D srmv2 srm://\?SFN=/pnfs/ # list V4 GM1g signal samples

> # Produce the ntuple locally
> cd ~/susy/samples08/fall08/NT2a/CMSSW_2_2_5/src/ # Go to ntuple production area
> cmsenv
> cd localproduction
> csh
> vim localsteercfg.csh # Change the number of the output name and input PAT file [do it yourself...]
> ./localsteercfg.csh # Makes the new ntuple production area
> cd GM1g_221_V4_NT2a_XX_ccsharesub/
> cmsenv
> cmsRun
> # Move the ntuple to the appropriate (local?) storage
> mv GM1g_221_V4_NT2a_XX_ccsharesub.root /data/tom/susysamples/fall08/GM1g/NT2a/.
> # Delete the PAT file
> cd /data/tom/susysamples/fall08/GM1g/PATLayer1_V4/
> rm GM1g_PATL1_V4_221_XX.root
> # Probably test the ntuple, just to be sure...


So far using V3 of the jet corrections...

Winter '09 samples found with:

find dataset where dataset like *photonjet* and dataset like *winter09*
Seem to be all GEN-SIM-DIGI-RECO and Fast Simulation. Is it worth looking at these yet?

2 Photon + jet

  /2PhotonJets_Mgg40-madgraph/Fall08_IDEAL_V9_v1/GEN-SIM-RECO 1001490   2_1_8  
  /2PhotonJets_Mgg40-madgraph/Fall08_IDEAL_V11_redigi_v1/GEN-SIM-RECO 1001853      

The signal:

Preliminary ntuples can be found on the God Box (cmsimperial002) in /data/tom/susysamples/summer08/gmsb/

The backgrounds

Photon + jets

Found on DBS with the following searches:

To find 2_2_3 fast sim winter09 samples, look up

find dataset where dataset like *photonjet* and release like *2_2_3*
