AIDA & Analysis Tools

Interface to AIDA

No dependence

Minimize coupling of components

Through abstract interfaces

Susanna Guatelli Geant4 Workshop 2004

Interfacing to Geant4

The analysis tools compliant with AIDA interfaces currently are:

– PI– JAS (Java Analysis Studio)– Open Scientist Lab

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

Analysis dynamic flow

Present situation

Use of AIDA 3.2.1 and PI 1.2.1

Create xml and hbook file containing– Histograms– Data point sets– Ntuples

Susanna Guatelli Geant4 Workshop 2004

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

Susanna Guatelli Geant4 Workshop 2004

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)

Susanna Guatelli Geant4 Workshop 2004

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

Susanna Guatelli Geant4 Workshop 2004

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 !
