Analysis in SPRACE 2012

Available Datasets:

All datasets available in SPRACE (which are AOD or AODSIM) can be found in this link. For 2012, we have available the following real data datasets:

• Single Muon
• Double Electron
• MET

General Analysis Strategy

In general, we advocate the following strategy:

1. Download datasets to SPRACE (optional)
2. Skim on basic reconstructed quantities // trigger bits. Run on GRID with CRAB. Save at SPRACE
3. Make Pattuples contataining everything you need for your analysis. Run on these using Condor. Save at SPRACE
4. Make basic ROOT ntuples containing very basic information for optimization // plots. Run on these at the interactive access server and/or your laptop.
