[Gate-users] GateMaterial Error in Voxelized Phantom simulation

[Fei Gao]

Dear Gate Users:



I tried several times, and now it works.



My solution:

1.Add gate work path to environmental variables.

2.Move voxelizedPhantom, voxelizedsource and all data file to the folder
mentioned in step 1

3. Run it



Maybe it is one of possible solutions.



BTW:  Does anybody know where I can find some Monte Carlo simulation results
(in sinogram format) of this kind of voxelized phantom?

Thank you for your help!



Sincerely



Fei

Dear Gate users,



I just reinstalled GATE, benchmarks and some examples run well,

But when I simulate a system of Voxelized phantom, the macros used are from
the example folders:

/examples/example_FULL_SIMULATION/YourScanner.mac

/examples/example_PHANTOM_SOURCE/Voxelized_Phantom_Source/VoxelizedPhantom.mac



I get error messages as follow:





/gate/world/daughters/name hof_brain
/gate/world/daughters/insert parameterizedBoxMatrix
   GateMaterialDatabase: did not load properties table for material
'Vacuum'.
     This is only a problem when OPTICAL PHOTONS are transported in this
material.'
/gate/hof_brain/geometry/insertReader interfile
GateVGeometryVoxelReader::GateVGeometryVoxelReader: m_voxelTranslator 0
/gate/hof_brain/interfileReader/insertTranslator range
GateVGeometryVoxelReaderMessenger::SetNewValue: newValue (translatorType) :
range
/gate/hof_brain/interfileReader/rangeTranslator/readTable range.dat

!!! GateMDBFile::LookForElementIndbStream:
        I could not find any section [Materials] in the material database
file.
        You should check the database file.
        Computation aborted!!!


*** G4Exception: Aborting execution ***
Aborted



However, when I checked the file GateMaterials.db, I do find “[Materials]”
in it.



Is there anybody encounter this problem? Or some suggestion?

Any help will be highly appreciated!



Many thanks





Sincerely

Fei
