Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.

over last few weeks I tried to understand how geant4e works. I have encountered several issues, submitted 4 tickets:
http://bugzilla-geant4.kek.jp/show_bug.cgi?id=1448 http://bugzilla-geant4.kek.jp/show_bug.cgi?id=1447 http://bugzilla-geant4.kek.jp/show_bug.cgi?id=1435 http://bugzilla-geant4.kek.jp/show_bug.cgi?id=1453
None of them triggered any human response.
Furthermore, I found this attempt of use of G4E for Belle II experiment: http://www-ekp.physik.uni-karlsruhe.de/pub/web/thesis/iekp-ka2012-18.pdf
Author struggles (1/3 of his thesis relates to Geant4e) and concludes on page 51, that: " [problems with covariance matrix propagation lead to ] several serious problems occurred, making it impossible to complete a properly running version, which led to the final abandonment of this project."
Further more he says (page 54) that a PHENIX member tried to use G4E and was not able to get it to work either.
The general feeling is Geant4E is not used by anyone in practice.
Given my experience so far I'm concerned in investing more of my time in to study of usability of Geant4E for my experiment.
Could you contact me with anyone who knows how Geant4E works and who could say it does work *correctly* for him/her?
