Hi Anastasia,
to print the information you can use the function Erxyzc() of TGeant3 (which corresponds to the fortran ERXYZC). If you look in TGeant3gu.cxx, in eustep(), it is already there for debugging:
if (geant3->Gcflag()->idebug * geant3->Gcflag()->iswit[2] != 0) geant3->Erxyzc();
you just have to enable it (outside the "if" statement) here in TGeant3gu.cxx, recompile geant3, run GEANE and it will print:

=====> starting GEANE tracking for MUON - NEPRED = 1 with options : LE
X Y Z R NAME NUMBER SLENG STEP DESTEP GEKIN MECHANISMS


so you can understand which particle is tracked, where (name is the name of the volume), the energy deposit and which is the process (DESTEP and MECHANISMS).

Cheers,
Lia.
