Hello,
I fixed the error. It was related to the changes in TGeant3 made by Andrea & Co., that required an update of the gconfig/g3Config.C file.

Here you are the comparison between cluster reconstructed energy for 1 GeV photons, for g3, g4 old and new:

index.php?t=getfile&id=3789&private=0

About the computation time:

G3: 148.66 s
G4 old: 27245.13 s
G4 new: 286.67 s


A good improvement, even if there are still strong differences.
Bye
