AnaEx01
|
||||
-------
|
||||
|
||||
This example shows the usage of histogramming with the
|
||||
analysis category.
|
||||
|
||||
To use the G4AnalysisManager the source/analysis category
|
||||
must have been reconstructed with one of the environment
|
||||
variable setted :
|
||||
G4ANALYSIS_BUILD_JAS
|
||||
G4ANALYSIS_BUILD_LAB
|
||||
G4ANALYSIS_BUILD_LIZARD
|
||||
This example shows the usage of histogram and tuple manipulations using
|
||||
an AIDA compliant system. In this example, all analysis manipulations
|
||||
(hooking an AIDA implementation, histo booking, filling, etc...) are
|
||||
concentrated in one class : AnaEx01AnalysisManager.
|
||||
|
||||
To use an analysis system with this example, the coresponding
|
||||
environment variable must be setted :
|
||||
G4ANALYSIS_USE_JAS
|
||||
G4ANALYSIS_USE_LAB
|
||||
G4ANALYSIS_USE_LIZARD
|
||||
To use an AIDA compliant analysis system with this example, the environment
|
||||
variables :
|
||||
G4ANALYSIS_USE
|
||||
G4ANALYSIS_AIDA_CONFIG_CFLAGS
|
||||
G4ANALYSIS_AIDA_CONFIG_LIBS
|
||||
must be properly set.
|
||||
|
||||
Then to cosntruct this example :
|
||||
The first one permits to validate/devalidate the AIDA analysis code
|
||||
in the example code. The two others permit to give the compilation
|
||||
and link flags of the AIDA compliant system used.
|
||||
An AIDA compliant system should define the command 'aida-config' that
|
||||
permits to retrieve the correct values. For example under some
|
||||
UNIX csh flavour :
|
||||
csh> source <your Geant4 setup script>.csh
|
||||
csh> source <AIDA_SYSTEM setup>.csh (or some equivalent)
|
||||
csh> setenv G4ANALYSIS_USE 1
|
||||
csh> setenv G4ANALYSIS_AIDA_CONFIG_CFLAGS `aida-config --cflags`
|
||||
csh> setenv G4ANALYSIS_AIDA_CONFIG_LIBS `aida-config --libs`
|
||||
csh> cd $G4INSTALL/examples/extended/analysis/AnaEx01
|
||||
csh> setenv G4ANALYSIS_USE_JAS 1
|
||||
csh> setenv G4ANALYSIS_USE_LAB 1
|
||||
csh> setenv G4ANALYSIS_USE_LIZARD 1
|
||||
csh> gmake
|
||||
|
||||
Working with the Lab package :
|
||||
----------------------------
|
||||
If working with the Lab package run the program
|
||||
from the analysis/Lab directory :
|
||||
csh> cd analyis/Lab
|
||||
csh> $G4WORKDIR/bin/$G4SYSTEM/AnaEx01 Lab
|
||||
It must produce a g4osc.root file that contains
|
||||
some histograms. You can visualize them with :
|
||||
csh> source <path>/Lab/<version>/cmt/setup.csh
|
||||
csh> oxm
|
||||
and click in File/session to execute the session.tcl
|
||||
file.
|
||||
|
||||
Working with jas :
|
||||
--------------------------
|
||||
If working with jas :
|
||||
For info, the CPP macros G4ANALYSIS_*_AIDA_* are used in the
|
||||
config/analysis.gmk file of the Geant4 GNUmakefile system.
|
||||
|
||||
Working with the Falsetto package :
|
||||
---------------------------------
|
||||
Falsetto is a little package containing a dummy
|
||||
AIDA analysis factory. It permits to check compilation
|
||||
and link of some user AIDA code without embarquing a
|
||||
full analysis system.
|
||||
|
||||
To reconstruct this example by using the Falsetto
|
||||
package (assuming that it is installed !), do :
|
||||
csh> source <your Geant4 setup script>.csh
|
||||
csh> source <some directory>/Falsetto/<version>/cmt/setup.csh
|
||||
csh> setenv G4ANALYSIS_USE 1
|
||||
csh> setenv G4ANALYSIS_AIDA_CONFIG_CFLAGS `aida-config --cflags`
|
||||
csh> setenv G4ANALYSIS_AIDA_CONFIG_LIBS `aida-config --libs`
|
||||
csh> cd $G4INSTALL/examples/extended/analysis/AnaEx01
|
||||
csh> $G4WORKDIR/bin/$G4SYSTEM/AnaEx01 jas
|
||||
The program will pend for a connection toward jas, then
|
||||
spawn jas :
|
||||
csh> <path_to_jas_bin>/jas
|
||||
csh> gmake
|
||||
|
||||
From jas panel, open a connection toward the AnaEx01 job :
|
||||
- File/Reconnect
|
||||
- Give no server name if running on same machine.
|
||||
- Next to end the connect panel.
|
||||
To run :
|
||||
csh> cd analyis/Falsetto
|
||||
csh> $G4WORKDIR/bin/$G4SYSTEM/AnaEx01
|
||||
At the beginning of output ;should appear :
|
||||
AIDA analysis factory not found.
|
||||
|
||||
When connection is established, the tree widget
|
||||
on the left of jas panel must display "G4Job".
|
||||
Click on the tree items to access an histogram.
|
||||
Double click on the histogram name to visualize it.
|
||||
|
||||
The histogram will update itself according time.
|
||||
The Falsetto URL is : http://www.lal.in2p3.fr/SI/Falsetto
|
||||
Falsetto is installed at CERN under /afs/cern.ch/sw/contrib.
|
||||
|
||||
Working with the OpenScientist/Lab package :
|
||||
------------------------------------------
|
||||
To reconstruct this example by using the OpenScientist/Lab
|
||||
package (assuming that OpenScientist is installed ! ) you have
|
||||
first to "setup" the environment of the Lab package and Geant4.
|
||||
The Lab package (and all OpenScientist packages) being handled
|
||||
by the CMT tools, you may have to setup the environment
|
||||
variable "CMTSITE" to execute site specific things in the chain
|
||||
of setup files of the OpenScientist packages. Then for example at CERN :
|
||||
csh> setenv CMTSITE CERN
|
||||
(DOS> set CMTSITE=CERN_WIN32 (for Windows))
|
||||
When done then do :
|
||||
csh> source <some directory>/Lab/<version>/cmt/setup.csh
|
||||
csh> source <your Geant4 setup script>.csh
|
||||
csh> setenv G4ANALYSIS_USE 1
|
||||
csh> setenv G4ANALYSIS_AIDA_CONFIG_CFLAGS `aida-config --cflags`
|
||||
csh> setenv G4ANALYSIS_AIDA_CONFIG_LIBS `aida-config --libs`
|
||||
csh> cd $G4INSTALL/examples/extended/analysis/AnaEx01
|
||||
csh> gmake
|
||||
|
||||
To run :
|
||||
csh> cd analyis/Lab
|
||||
csh> $G4WORKDIR/bin/$G4SYSTEM/AnaEx01
|
||||
|
||||
It must produce an AnaEx01.root file that contains
|
||||
some HCL histograms and a Lab tuple (stored as a ROOT/TTree).
|
||||
|
||||
To plot some histograms, spawn the Lab interactive tool with :
|
||||
csh> onx
|
||||
(DOS> onx (for Windows))
|
||||
click in File/Python to map a file chooser, choose AnaEx01.py
|
||||
to execute the AnaEx01.py that contains a Python script that
|
||||
do some analysis over the AnaEx01.root file (it gets an histo, plots it
|
||||
in a first drawing region, gets the tuple, books and fills another histo
|
||||
from the tuple colum and plots it in another drawing region).
|
||||
|
||||
The AnaEx01.C file could also be used, within the ROOT tool,
|
||||
to see a projection of the first column of the tuple contained
|
||||
in the AnaEx01.root file. For example :
|
||||
csh> root
|
||||
root[0] .X AnaEx01.C
|
||||
|
||||
The OpenScientist URL is : http://www.lal.in2p3.fr/OpenScientist
|
||||
OpenScientist is installed at CERN under /afs/cern.ch/sw/contrib.
