[Gate-users] DoseActor not recording any dose (empty 0's files)

[David Sarrut]

Hi,

hard to say, please check any overlap in the volumes? If a volume A is
included in a volume B, but not defined as a daughter of B, it may be
ignored by Geant4 ...
Maybe start with as few volume as possible and add them one by one to check
...

HTH,
David
