How to run the data analysis code
 Work area (PDSF) 
/global/u1/x/xiao00/work/run12 
STAR library
SL12d

In /global/u1/x/xiao00/work/run12

1 Code under StRoot
(1) StPicoDstMaker/ PicoDst see http://rnc.lbl.gov/~xdong/SoftHadron/picoDst.html 
(2) StDmesonMaker/ Read Pico to save  analysis tree for the charm analyis, saved  the hadron and electron candidate. 
(3) StNpeMaker/ Read DmesonTree make the Npe analysis 
(4) macros/ macros to run the main program
(5) StTriggerUtilities/ Trigger simulator
(6) StEmbeddingAnaMaker   Read embedding save the embedding analyis tree
(7) StEmbeddingAna Read embedding tree and make the embedding analysis  

2. How to run the code make test sampe  and sumbit the job   

(1) Run test sample (PDSF)
    cd /global/u1/x/xiao00/work/run12 
    starver SL12d
    ./cons.sh
    ./run_Npe.test.csh

(2) Sumbit jobs (PDSF)
cd /global/project/projectdirs/star/pwg/starhf/Xiaozhi/Run12_pp/Data
./clear.sh
star-submit  submit.xml
The jobs will take  2-3 hours, after jobs finishde( qstat -u xiao00 | wc) 
cd /global/project/projectdirs/star/pwg/starhf/Xiaozhi/Run12_pp/Data/production
hadd hist.root *.root (hist.root saved all the histogram)
