Common Analysis Format, CAFe Framework and CAF Common Tools

CAF communication

• A mailing list has been setup for discussion of CAF: d0-caf-users@fnal.gov
  • How to subscribe.
  • View archive.
• D0 Wiki CAF page.

CAF Trees for p17 Data

• SAM definitions for p17 data and MC can be found on the p17 Fixed Data and Monte Carlo for Summer 2006 web page.
• SAM definitions for p20 data and MC can be found on the p20 Data and Monte Carlo for Summer 2007 web page.

Tutorials and documentation

• 2007 overview of available common tools.
• To start your analysis in CAF: the 2005 CAF common tools tutorial and 2007 updates.
• To understand CAF and CAFe and start developing using CAFe framework: the Vancouver tutorial.
• A complete analysis example can be found in Gavin's Manchester 2006 Tutorial and Mike's MSU 2007 Tutorial.
• A hypertext version of the current CAF tree classes is available.
• CAFe Frequently Asked Questions Wiki page.
• The CAF format was developed by the Data Format Working Group. You can find there the initial report of the first working group and the content document of the implementation group.

Installation

Follow this instruction. The recent packages versions list available here.

Stand-alone Code

A tar.gz file with code for the stand-alone version can be found here. This tarball corresponds contains packages listed here. Installation and test instructions:

• Create the working directory (e.g. work_dir)
• cd work_dir
• Save caf-p18.07.00.tar.gz file to this directory
• tar -zxvf caf-p18.07.00.tar.gz
• You can update the packages with the most recent versions listed here.
• Check that ROOTSYS environment variable is setup properly, LD_LIBRARY_PATH contains $ROOTSYS/lib and $ROOTSYS/bin included to the PATH
• source tmb_tree/tools/setup-standalone.[c]sh
• gmake
• Add $PWD/bin to your PATH variable
• Copy any CAF tree to your computer (see available CAF tree here)
• Add list of the CAF MC root trees to the file "filelist.dat". If you want to use the data trees, you need to change the DQ definition in the file test.config (the default is for MC).
• cafe ./caf_util/configs/test.config
• verify that test.html and test.root are filled properly

CAF Analysis related tools and packages

• caf_util : common CAF tools
• caf_mc_util : common MC CAF tools
• caf_dq, dq_util, dq_defs : the standard data quality selection (bad runs, bad lbns removal, event quality selection).
• The b-tagging tools described at the B-ID Wiki page. See Aran's talk abouth b-tag selectot in caf_util.
• caf_eff_utils, eff_utils : applying data / MC efficiency corrections.
• caf_trigger, eff_utils : applying trigger efficiency to MC.
• Instruction how to run muo_cert (program for measurement muon ID and trigger efficiencies) available at Wiki page.

  Meetings

  After the initial release of CAF, there are no more regular meetings of the working group or developers. We will have occasional meetings in the context of the Common Samples Group.
