Introduction

There will be an Analysis Jamboree at ANL ASC from 9 Dec through 12 Dec. This time, the emphasis will be on looking at the recent single beam and cosmic data.

This workshop will be similar, and related, to the BNL Jamboree in the following week, 15-18 December.

As usual, the Jamboree will be organized so that participants at all levels proficiency with the ATLAS software environment will benefit. There will be rather few talks and large amount of working period when participants may works on goals that they set themselves, and obtain help and guidance from the ANL ASC staff.

We will cover:

• Starting ATLAS analyses
  • Learning to make ntuples from AOD and DPDs
  • Generating Monte Carlo samples
  • Running on the GRID
• Using FDR2c data: this time with empahsis on:
  • Using DPDs
  • Using TAGs on the GRID
• Analyzing cosmics and single-beam data
• Using the ANL PC Farm: We are working on a low-cost PC Farm suitable for ATLAS Tier 3 analyses. Currently, we have a prototype system operating at the ASC. We will provide demonstrations, and those interested will be able to try the system out.
  • Here is a description of the PC Farm.

This Wiki will be continuously updated from now on to the end of the Jamboree. Working Examples

Structure of the Workshop

The workshop is designed, as with our previous workshop/jamborees, for the participants to gain as much practical experience with ATLAS analysis as currently possible. To this end, we will use the Full Dress Rehearsal-2c (FDR-2c) data, which is the closest approximation of the real physics data we currently possess as well as the Cosmics and the single beam data taken earlier this year.

We will set up the workshop to mainly work off of Athena version 14.2.23. Material provided below are meant to start you off. You can start at whatever level is appropriate for you.

For your reference, a description of the ATLAS analysis model is Here. and an introduction to Athena and StoreGate is Here.

Beginner

1. Set up your ANL ASC account. The instructions are here.
2. Set up and run athena "hello world". General instructions are HERE. 14.2.23 seems to have dispensed with "HelloWorldOptions.py". Copy it into your ../run directory from ~ryoshida/tmp/jamboree/HelloWorldOptions.py.
3. Set up and run athena "Analysis Skeleton" on an AOD file and produce a root n-tuple. A general instruction from the ATLAS Twiki Here can be followed. An example MC AOD data file that can be used is...

   • /data/nas2/users/ryoshida/sep_jamboree_mc/
   • /data/nas2/users/ryoshida/fdr08_run2c/ (FDR2c data)
   • Use ln -s command to link to the data files rather than copying it into your run directory. (or specify the full input file path in your AnalysisSkeleton_topOptions.py file.
4. Modify the default analysis and produce your own plots or n-tuple variable. A working example is in Modify AnalysisSkeleton.
5. Run the same job on the Grid using pathena. The instructions are here.

Intermediate

1. Run your analysis job on FDR-2 AOD locally to produce an analysis n-tuple. Here is an example of a Prompt Photon analysis (works with 14.2.23 as well as 14.2.20).
2. Run your analysis on an FDR-2 DPD locally.
3. Build a job to run over a Cosmics ESD locally. A working example is in Analyzing Cosmics ESDs.
4. Analyze Cosmics CBNTs. A working example is in TileCal Cosmic CBNT example.
5. Build a job to run over a 1Beam data ESD locally. A working example is in Analyzing 1Beam ESDs.
6. Find the luminosity for the FDR2 sample you analyzed. Getting Luminosity.
7. Generate some Monte Carlo locally.
8. Run your job on the Grid. The instructions are here.
9. Submit real analysis job to the grid. See instructions

Advanced

1. User TAGS to select the FDR-2 data. The instructions are in Using TAGs.
2. Run your job on the ANL PCFarm. The instructions are in Running on ANL PC Farm.
3. Using PROOF at BNL.
