[Gate-users] error :Voxelized source

[Susana Branco Silva]

Hi Sonal,

 

The warning message: 

 

“I/O warning : failed to load external entity "Materials.xml"
GateMaterialDatabase: did not find the Materials.xml file: no properties
read for material 'Water'

This is only a problem when OPTICAL PHOTONS are transported in this
material.”

 

is only a problem if you want to track optical photons. To track optical
photons, you will need to add the description of optical properties for
materials of interest in the Materials.xml file.

 

Even if this message appears every time, there is no problem in the run. The
problem is that Gate doesn't find the Materials.xml except when this file is
in the run directory. So if you copy this file in the folder from where you
launch Gate, the message "I/O warning : failed to load external entity
"Materials.xml" will disappear but you will get a new warning message, like
the following:

"GateMaterialDatabase: did not load properties table for material 'xpto'
(
)”, but don't worry because they don't intervene with the right
functionality of GATE.

 

I think this is “your” problem


 

Cheers,

 

Susana Branco Silva

Subject: [Gate-users] error :Voxelized source

 

hello gate-users,

 

I am trying to run the voxelized phantom of the hoffman brain given in 

the gate examples and this is the warning that i am getting.

 

GateGeometryVoxelInterfileReader::ReadFile: WARNING: voxel not added 

(material translation not found); value: 5

GateGeometryVoxelInterfileReader::ReadFile: WARNING: voxel not added 

(material translation not found); value: 2

GateGeometryVoxelInterfileReader::ReadFile: WARNING: voxel not added 

(material translation not found); value: 2

GateGeometryVoxelInterfileReader::ReadFile: WARNING: voxel not added 

(material translation not found); value: 1

 

 

Can someone tell me what the problem is? Is it related to the warning

I/O warning : failed to load external entity "Materials.xml"

    GateMaterialDatabase: did not find the Materials.xml file: no 

properties read for material 'Water'

      This is only a problem when OPTICAL PHOTONS are transported in 

this material.'

 

Please help.

Thanks,

Sonal
