Example B4dScoreWriter
|
|
----------------------
|
|
|
|
This example demonstrates saving the Geant4 scorers hits in form of ntuples in a Root
|
|
file using Geant4 analysis tools.
|
|
|
|
The example is completely based on basic B4d example, the storing scorers hits is activated
|
|
in the main () function with instantiating G4ScoreNtupleWriter.
|
|
In difference from the B3aScoreWriter example, the G4AnalysisManager is explicitly used
|
|
in this example and the ntuples with scorers hits are saved in addition to the histograms
|
|
and ntuples created in B4RunAction.
|
|
|
|
The G4ScoreNtupleWriter and G4ScoreNtupleWriterMessenger classses are provided in
|
|
the 'scoreWriter' directory in this example. These classes are fully independent from
|
|
the example classes and they can be reused in any Geant4 application.
|
|
|
|
The Geant4 UI command defined in G4ScoreNtupleWriterMessenger can be used to choose
|
|
the output file type, the file name and the level of verbosity:
|
|
|
|
/score/writerType root
|
|
/score/fileName name
|
|
/score/writerVerbose 1
|
|
|
|
How to build
|
|
---------------
|
|
|
|
An additional step is needed when building the example with GNUmake
|
|
due to using the extra 'scoreWriter' directory:
|
|
|
|
% cd path_to_B4dScoreWriter/B4dScoreWriter
|
|
% gmake setup
|
|
% gmake
|
|
|
|
This will copy the files from scoreWriter in the example include and src;
|
|
to remove these files:
|
|
% gmake clean_setup
|
|
|
|
How to run
|
|
-------------
|
|
|
|
- Execute exampleB4dExt in the 'interactive mode' with visualization
|
|
% ./exampleB4dExt
|
|
and type in the commands from run1.mac line by line:
|
|
Idle> /run/initialize
|
|
Idle> /control/verbose 2
|
|
Idle> /tracking/verbose 2
|
|
Idle> /run/beamOn 1
|
|
Idle> ...
|
|
Idle> exit
|
|
or
|
|
Idle> /control/execute run1.mac
|
|
....
|
|
Idle> exit
|
|
- Execute exampleB4dExt in the 'batch' mode from macro files
|
|
(without visualization)
|
|
% ./exampleB4dExt -m run2.mac
|
|
% ./exampleB4dExt -m exampleB4dExt.in > exampleB3.out
|
|
|
|
See the B3 example README for the further documentation of the basic B3 example.
