[gate-users] voxelized phantom

[Uday Tipnis]

Hi,

I'm trying to use a voxelized phantom in Gate and am experiencing some 
problems. Following is the macro I use to define the phantom:

/gate/world/daughters/name ncat
/gate/world/daughters/insert replicaMatrix
/gate/ncat/geometry/insertReader image
/gate/ncat/imageReader/insertTranslator range
/gate/ncat/imageReader/rangeTranslator/readTable range.dat
/gate/ncat/imageReader/rangeTranslator/describe 1
/gate/ncat/imageReader/readFile myo_atn.dat
/gate/ncat/attachPhantomSD

I'm simulating a cylindricalPET system and all commands are accepted and 
no warnings/errors are issued as Gate runs. But "gateCoincidences.dat" 
remains empty. If I comment out the above macro, I get coincidences as 
expected. I have added some new materials to the "GateMaterials.db" file 
but they are accepted by Gate and don't seem to be a problem. Anyone who 
has used a voxelized phantom successfully, please help.

Thanks in advance,

Uday
