Interfacing to Geant4
The analysis tools compliant with AIDA interfaces currently
are:
– PI
– JAS (Java Analysis Studio)
– Open Scientist Lab

• 2D histograms
• Ntuple

Present situation
Use of AIDA 3.2.1 and PI 1.2.1
Create xml and hbook file containing
– Histograms
– Data point sets
– Ntuples

Interactive analysis tool
Lizard / Grace is not maintained anymore
HyppoDraw
– We have to test and start to use it
– It is possible to plot 2D histograms
– Not usable in batch mode

Comments
More coordination between Geant4
Collaboration and the analysis Group
AIDA and PI are the analysis standards
of the Geant4 advanced examples
– The analysis Groups should respect the
time schedule (fixed to be compatible with
the Geant4 releases)

Suggestion
Add new functionality and not remove functionality:
Plotting is not available anymore in the Geant4
applications
This is not the first time of removing functionality:
– the capability of plotting 2D histograms was remove in the
passage from the QPlotter to Grace;
– the management of ntuples disappeared for few months
This behaviour should be deprecated

Conclusions
Fruitful collaboration
– Analysis Groups are open to Geant4 User Requirements and
collaborative
– Geant4 Collaboration provides feedback on the analysis tools
Explore, use, compare all the AIDA – compliant analysis
tools
Thanks to the analysis Groups for the user support !
