STAR ENDCAP HOWTO's

    Processing of STAR .daq events without StRoot framework.
    This package allows to convert any data contained in the STAR DAQ files (.daq) to a StRoot-free standard ROOT trees. For now we have added a subset of trigger data , L3 tracks and EEMC data.

  1. Installation:
    - login to eemcdb@rcas6nnn, cd siew , all works there
    - or read this instruction to install it anywhere on linux
  2. extract .daq files from HPSS
    - the official place is /star/data03/daq/2003/ddd/ where 'ddd' is day. Note, you can't extract at once more then 280 file sequences due to the quota.
    - create directory for given day, go there
    - execute Piotr's script: ~balewski/root2003/gfhpss.sh 4124031 <-- run number you want, wait 5-30 minutes for .daq files
  3. convert .daq -->ezTree.root
    - go to ~/siew
    - edit siew.sh so it points to .daq files, select subset if needed
    - execute: siew.sh 4124031
    - it takes few minutes per file seq (i.e. many hours per STAR run) to create the ezTree, due to slow data transfer from /star/data03 --> rcas6nnn
  4. print raw data with 'dumpTree.C' (edit/change it as needed)
    root -b dumpTree.C
