[Gate-users] About using two systems during one simulation

[Wuwei Ren]

Hi, dear GATE-User,

Recently I am working on a project in which we need two scintillators
to record the hits at the same time. However, they belong to different
systems, say SPECThead and scanner. It seems difficult to attach
CrystalSD to both of the scintillators. I have the following warning
text:


Code:
/gate/systems/scanner/level1/attach SPECThead2
/gate/systems/scanner/level2/attach crystal_2
/gate/crystal_2/attachCrystalSD

Information about errors:
[GateCrystalSD::PrepareCreatorAttachment]:
Volume 'crystal_2' belongs to system 'systems/scanner'
while the crystalSD has already been attached to a volume from another
system ('systems/SPECThead').
Attachment request ignored --> you won't have any hit output from this volume!!!

[GateVObjectCreator::AttachCrystalSD]:
Can not attach crystalSD!

What should I do to attachcrystalSD to both of them?

Thanks!

best regards,
Wuwei Ren
