Use of Analysis Tools

1
Use of Analysis Tools

• Geant4 Workshop 2004, Catania
• Susanna Guatelli, INFN Genova

2
Interface to AIDA
Through abstract interfaces
? No dependence ? Minimize coupling of
components
AIDA Analysis Tools
3
Interfacing to Geant4

• The analysis tools compliant with AIDA interfaces
  currently are
• PI
• JAS (Java Analysis Studio)
• Open Scientist Lab

4

• How to produce
• 1D histograms
• 2D histograms
• Ntuple

5
Analysis dynamic flow
6
Present situation

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

7
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

8
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)

9
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 !
