10 JSF JSF provides common framework for studies using  Quick Simulator  Jupiter/Satellites To start interactive session of jsf, do $ jsf gui.C JSF control panel popes up

11 Using JSF Control Panel Controls menu  run mode  generator type  generator parameters  pythia –event type  zh  save parameters Next Event button

12 Batch Run root option:  -b : run without X  -q : quit at the end jsf option  --maxevt=N : N is number of events $ jsf -b -q --maxevt=100 gui.C

13 JSF Basics

14 JSF features - 1 JSF is based on ROOT  User needs to lean just one language, C+ JSF provides a framework for modular analyses  Common framework for event generation, detector simulation, and analyses.  Same framework for beam test data analysis Unified framework for interactive and batch jobs  GUI for control of an interactive run Histogram and event display packages included  A file similar to.rootrc is used to set parameter.  Default values an be overidden by command line argument at run time.

15 JSF Features – 2 Object I/O  Each modules can save/read their event data as branches of a root tree.  Job parameters, histograms, ntuples and private analysis tree can be saved in the same file Packages  Included in the release  Pythia6.3, Bases/Spring++, ZVTOP, JETNET, BSGEN Provided as separated packages  Physsim (Event generators and analysis utilities)  LCLIB (QuickSim, Helas)  Jupiter (Geant4)  Uranus/Satellites

16 JSF Conponents Libraries ( $JSFROOT/lib )  Pre-compiled C++ classes to build JSF application such as libJSFGenerator.so, libJSFQuickSim.so, … Executables (main program ) ($JSFROOT/bin)  “jsf” command : built with ROOT+libJSF.so Macros ($JSFROOT/macro)  C++ program is used as Macro thanks to CINT (No need to compile and link)  In JSF, Macros are used to set run parameters and provide a simple analysis code. gui.C, GUIMainMacro.C, UserAnalysis.C

17 JSF Kernel JSF is a framework for event-by-event data analysis Provides a modular framework suitable for analysis consists of several sub-detectors Job flow control Create modules Jon Initialization Begin Run Event analysis End Run Job Termination  Job flow is controlled by a class, JSFSteer  Analysis modules are inherited from a class, JSFModule  Member functions of JSFModule Initialize(), BeginRun(..), Process(…), EndRun(), Terminate() JSF job flow concept A simple example without Macros is prepared in $JSFROOT/example/ZHStudy

18 JSF Kernel - FileIO  A class, JSFEventBuf, is defined by JSFModule  It is used to define branch of a ROOT Tree ( used to save/get event data )  JSFModule  JSFEventBuf : 1-to-1 correspondance  Information of JSFModule written in a root file is used to define branch for read-in data.  In a user program,  To get pointer to JSFModule objects, mod= (JSFModule*) gJSF->FindModule(“module_name”)  To get pointer to JSFEventBuf objects, buf=(JSFEventBuf*)mod->EventBuf()

19 Access to JSFModule and JSFEventBuf In script  JSFSteer *jsf (defined in gui.C) jsf->GetEventNumber(); JSFXXX *mod=(JSFXXX*)jsf- >FindModule("JSFXXX"); JSFXXXBuf *buf=(JSFXXXBuf*)mod->EventBuf(); In compiled code,  JSFSteer *gJSF (defined in JSFSteer.h)

20 Useful Web information JSF Class Documents CVS 

21 Parameter file All parameters are managed by JSFEnv class  In the userprogram, they are obtained by a method, JSFEnv::GetValue(“Parameter.name”,default) At run time, paremetercan be changed by three method  In a file, jsf.conf Parameter.Name: value #!argname # comments ….  As a command line argument, like $ jsf –argname=value gui.C  Through the popup menues of JSF Control Panel Each user can add their own menu by a function, UserMenu() argname is an alias of Parameter.Name used to parse command line argument

22 Macro in JSF In JSF, macros ( xxx.C file ), are used extensively to define type of jobs and job parameters. GUIMainMacro.C : Define a standard set of modules and their parameters gui.C : Load GUIMainMacro.C and libraries for GUI UserAnalysis.C : An sample user macro file for Initialization, event analysis and drawing histogram Important macro files in $JSFROOT/macro directory

23 JSF – First example in SimTols Examples inSimTools $ cd [SimTools]/examples/JSF_QuickSim/exam01 $ jsf gui.C JSF control panel popes up

24 UserAnalsis.C Example in $JSFROOT/macro/UserAnalysis.C Three functions:  UserInitialize() : Called at Job initialization define Histgrams, etc.  UserAnalysis() : Called at each event for event analysis  DrawHist() : Called to draw histogram
