Compiling and running
---------------------
To compile this example you need AIDA 3.0 installed. To link
Can be compiled and executed on a RedHat-7.3 system with gcc-3.2.3
compiler and the tcsh shell.
To compile this example you need AIDA 3.2.1 installed. To link
and run it you need a AIDA compliant analysis package. The
GNUmakefile of this example shows how to use Anaphe as analysis
package.
The following list shows what to do if you are at CERN using rehat73
and gcc-3.2 and the tcsh:
1) set the following variables (for example):
setenv ANAPHETOP /afs/cern.ch/sw/lhcxx
(or if installed in opt: /opt/Anaphe/5.0.5)
setenv AIDA_DIR /afs/cern.ch/sw/contrib/AIDA/3.0/src/cpp
(or if installed in opt: /opt/AIDA/3.0.0/3.0.0/AIDA/3.0/src/cpp)
2) Source the script:
source $ANAPHETOP/share/LHCXX/5.0.5/scripts/setupAnaphe.csh
This should set the LD_LIBRARY_PATH and the PATH environment to find the
lizrd executable and Anaphe libraries and header files.
It also sets the environment variable PLATF.
3) and add to lirary path the following directories:
setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:${G4WORKDIR}/lib/${G4SYSTEM}:${G4WORKDIR}/tmp/${G4SYSTEM}/exampleB02
GNUmakefile of this example shows how to use AIDA through PI as
analysis interface.
Histograms are saved in HBOOK format. It can be displayed with PAW or
compatible packages.
You need to set the following variables in your environment:
"G4ANALYSIS_USE"
"PI_BASE_DIR" (where PI has been installed)
Finally, source the script setupPI.csh.
Now you should be able to run gmake and to run exampleB02.
The example stores the plot in the file b02.hbook.
To look at the histogram using lizard you also may use Anaphe 5.0.5
http://anaphe.web.cern.ch/anaphe/index2.html.
Files in B02:
B02plot.py: a simple script that may be executed from a lizzard session
to show the plot created by running the exampleB02.
To look at the histogram using lizard you also may use PI 1.2.1
http://cern.ch/PI.
Example B03
===========
This example uses Geant4 and in particular importance sampling and
scoring through python. It creates a simple histogram. It's ment
scoring through python. It creates a simple histogram. It's meant
to demonstrate how to use a customized scorer and importance sampling
in combination with a scripting language, python.
Geant4 code is executed from a python session. Therefore, swig is used
to create python shadow classes and to generate the code necessary to
use the Geant4 libraries from a python session.
For simplicity it is recommended to use Anaphe. Anaphe comes with
python and swig installations.
See http://anaphe.web.cern.ch/
It can be built and run using PI: http://cern.ch/PI.
At the end a histogram called "trackentering.hbook" is created and can be
displayed using standard packages (such as PAW).
Building, compiling and running
-------------------------------
Follow similar steps as for example B02. If you already have
the environment set up for example B02 jump to point 3 below:
You need to set the following variables in your environment:
"G4ANALYSIS_USE"
"PI_BASE_DIR" (where PI has been installed)
"SWIG_BASE_DIR" (where SWIG 1.3.15 has been installed)
Finally source the script setupPI.csh.
1) set the following variables (for example):
setenv ANAPHETOP /afs/cern.ch/sw/lhcxx
(or if installed in opt: /opt/Anaphe/5.0.5)
setenv AIDA_DIR /afs/cern.ch/sw/contrib/AIDA/3.0/src/cpp
(or if installed in opt: /opt/AIDA/3.0.0/3.0.0/AIDA/3.0/src/cpp)
2) Source the script:
source $ANAPHETOP/share/LHCXX/5.0.5/scripts/setupAnaphe.csh
3) and add to lirary path the following directories:
setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:${G4WORKDIR}/lib/${G4SYSTEM}:${G4WORKDIR}/tmp/${G4SYSTEM}/exampleB03

You may run gmake now.
You should be able to execute the file B03RunApplication.py from your
shell or from a lizard session now.
The histogram is displayed only if the script is beeing ran
from lizard.
At the moment the plotting is not available using a python script, but
it is planned in future releases. A histogram is created and later displayed
using standard analysis packages.

session. In case it is executed from lizard it creates a plot
with a histogram.
