[Gate-users] multiple sensitive detectors

[Marc Chamberland]

Hi Benjamin,

Your problem is that you have not defined a valid system in Gate. Please a look at this section of the User's guide: http://wiki.opengatecollaboration.org/index.php/Users_Guide_V6.2:Defining_a_system

You can't call your main volume mainVol and attach modules to it. You have to use one of the specific system keywords such as 'scanner', 'CTscanner', etc. Then, you can only attach the components which belong to this particular system type. For example, 'rsector', 'module', etc. for 'cylindricalPET'.

Hope this helps.

Cheers,
Marc

Hello All:

I am trying to get familiar with the GATE system by attempting to modify
and replicate various examples and benchmarks provided with the GATE
install.

I am currently trying to set up more than one sensitive detector and am
running into a very strange error.  I get the error:

***** COMMAND NOT FOUND </gate/systems/mainVol/module/attach module> *****
***** Batch is interrupted!! *****

In addition, there are twelve lines of:

Warning in <TBranch::TBranch>: No name was given to the leaf number '0' in
the leaflist of the branch ''.

But, I assume this last error is due to the improper set up.

I am following the example in the example_TrackerDetector; and they have a
line EXACTLY like my first error in their geometry construction
(/gate/systems/cylindricalPET/module/attach module - of course the main
name is different).

I think I must be missing something with the attachment of the entire
system and would appreciate any assistance someone could offer.

thank you,
Benjamin
