UserAnalysis.C
» Example in $JSFROOT/macro/UserAnalysis.C
» Three functions:
~ UserInitialize() : Called at Job initializationdefine Histgrams, etc.~ UserAnalysis() : Called at each eventfor event analysis~ DrawHist() : Called to draw histogram
jsf/ex1/UserAnalysis_1.C
Batch run$ jsf -b -q --maxevt=100 gui.C
» root option:
~ -b : run without X~ -q : quit at the end» jsf option
~ --maxevt=N : N is number of events
Set parameters
» In a file, jsf.conf
» Command line arguments$ jsf -conf=conf_file --optionN=valueN .... gui.C
~ conf_file : a parameter file name~ optionN=valueN: parameter name and its value
Format of jsf.confParameter.name : value#!option_name# comment-1# comment-2
Access JSFModule and JSFEventBuf
» In scipt
