Yes, it is possible through Anaphe.

Anaphe is one of the AIDA-compliant analysis tools. It offers, among other options, a persistency implementation through HBook: that is, you can produce histograms/ntuples, which can be then read in and manipulated by PAW (or by Lizard).

You can find examples how to do so in Geant4 advanced examples (geant4/examples/advanced/underground_physics/ or /brachytherapy/, for instance), and further information in http://www.ge.infn.it/geant4/examples/analysis.html and in http://cern.ch/anaphe

Try to run the advanced examples and to open the histogram file produced with PAW: you will see that it works!

By the way, the basics of how to book/fill/store histograms and ntuples using AIDA in a Geant4 application are very easy to learn, especially following the advanced examples, so you shouldn't be worried about having to invest much time into studying them.

As a bonus, your same user code would be still valid, without needing to change a single line, if one day you decide to move to one of the modern OO analysis tools, whichever would be the underlying concrete implementation (loaded as a shared library: Anaphe with Hbook, Anaphe with another persistency option, JAS and Java etc.) you may want to use.

Hope it helps.

Best wishes,

Maria Grazia Pia
