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.
- Installation:
- login to eemcdb@rcas6nnn, cd siew , all works there
- or read this instruction to install it anywhere on linux
- 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
- 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
- print raw data with 'dumpTree.C' (edit/change it as needed)
root -b dumpTree.C
