1.As the warning said"Otherwise, please copy the Materials.xml file
from the gate-source directory in the directory where you run your
main macro","Materials.xml" should be put in the directory $PWD
where you run your Gate<br>
2.Before the visualize,you'd better "/control/execute mac/visu.mac".
Or organize your own "visu.mac"<br>

<div>Hi dear Gate users</div>
<div><br>
</div>
<div>I have just started to use vGate (virtual Gate) and have
some problems that I don't know how to solve them. here are my
problems:</div>
<div><br>
</div>
<div>I tried to define a geometry after I defined the directory
of the materials, but Gate stopped running.</div>
<div>here is my macro:</div>
<div><br>
</div>
<div>
<div>Idle> /gate/geometry/setMaterialDatabase
/home/gate/Progs/Gate//gate_v6.2/Materials.xml</div>
<div>Idle> gate/world/daughters/name H</div>
<div>Idle> gate/world/daughters/insert box</div>
<div><u>/home/gate/Progs/Gate/gate_v6.2/source/geometry/src/GateMaterialDatabase.cc
(l.132): GateMaterialDatabase: could not find the
definition for material 'Vacuum' in material files</u></div>
<div><u>gate@vgate:~$ </u></div>
</div>
<div><u><br>
</u></div>
<div>even when I changed the directory from "Materials.xml" to
"GateMaterials.db", some warnings appeared as follow:</div>
<div><br>
</div>
<div><br>
</div>
<div>
<div>Idle> /gate/geometry/setMaterialDatabase
/home/gate/Progs/Gate/gate_v6.2/GateMaterials.db</div>
<div>Idle> gate/world/daughters/name H</div>
<div>Idle> gate/world/daughters/insert box</div>
<div><u>I/O warning : failed to load external entity
"Materials.xml"</u></div>
<div><u>I/O warning: Discard the previous warning if your
simulation doesn't transport OPTICAL PHOTONS. </u></div>
<div><u>Otherwise, please copy the Materials.xml file from the
gate-source directory in the directory where you run your
main macro.</u></div>
<div><u><br>
</u></div>
<div>I ignored the warning and continued entering commands,
but I faced similar problem when I set "water" for material:
</div>
</div>
<div><br>
</div>
<div>
<div>Idle> /gate/geometry/setMaterialDatabase
/home/gate/Progs/Gate/gate_v6.2/GateMaterials.db</div>
<div>Idle> gate/world/daughters/name H</div>
<div>Idle> gate/world/daughters/insert box</div>
<div>I/O warning : failed to load external entity
"Materials.xml"</div>
<div>I/O warning: Discard the previous warning if your
simulation doesn't transport OPTICAL PHOTONS. </div>
<div>Otherwise, please copy the Materials.xml file from the
gate-source directory in the directory where you run your
main macro.</div>
<div>Idle> gate/H/geometry/setXLength 10. cm</div>
<div>Idle> gate/H/geometry/setYLength 20. cm</div>
<div>Idle> gate/H/geometry/setZLength 30. cm</div>
<div>Idle> gate/H/setMaterial water</div>
<div><u>/home/gate/Progs/Gate/gate_v6.2/source/geometry/src/GateMaterialDatabase.cc

definition for material 'water' in material files</u></div>
<div><u>gate@vgate:~$</u> </div>
</div>
<div><br>
</div>
<div>once again, when I replaced "water" with "LSO", warning
message appeared: </div>
<div> </div>
<div><br>
</div>
<div>
<div>Idle> /gate/geometry/setMaterialDatabase
/home/gate/Progs/Gate/gate_v6.2/GateMaterials.db</div>

<div><u>Otherwise, please copy the Materials.xml file from the

<div><br>
</div>
<div>I also tried to visualize the volume created, but after I
entered the following commands it did not work and no
graphical volume was shown.<br>
</div>
<div><br>
</div>
<div>Idle> gate/H/vis/setColor red </div>
<div>Idle> gate/H/vis/forceWireframe</div>
</div>
<div><br>
</div>
<div><br>
</div>
<div>I would be grateful to guide me.</div>
<div>Thank you so much of your time </div>
