I followed up the instructions to install the Geant10.04.p02 and Gate 9.0. Example B1 is fine. All figures could be seen. But I failed to conduct a PET geometry defining on the first pages of the GATE guideline. Only the frame showed up. I could not see any system or boxes in the viewer following the command lines. Anyone could help get me out of this situation. I will appreciate. <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>/vis/open OGLSX</span></p><p class=MsoNormal><span lang=EN-US>/vis/viewer/reset</span></p><p class=MsoNormal><span lang=EN-US>/vis/viewer/set/viewpointThetaPhi 60 60</span></p><p class=MsoNormal><span lang=EN-US>/vis/viewer/zoom 1</span></p><p class=MsoNormal><span lang=EN-US>/vis/viewer/set/style surface</span></p><p class=MsoNormal><span lang=EN-US>/vis/drawVolume</span></p><p class=MsoNormal><span lang=EN-US>/tracking/storeTrajectory 1</span></p><p class=MsoNormal><span lang=EN-US>/vis/scene/endOfEventAction accumulate 10</span></p><p class=MsoNormal><span lang=EN-US>/vis/viewer/update</span></p><p class=MsoNormal><span lang=EN-US>/gate/geometry/setMaterialDatabase misc/GateMaterials.db</span></p><p class=MsoNormal><span lang=EN-US>/gate/world/geometry/setXLength 40. cm</span></p><p class=MsoNormal><span lang=EN-US>/gate/world/geometry/setYLength 40. cm </span></p><p class=MsoNormal><span lang=EN-US>/gate/world/geometry/setZLength 40. cm </span></p><p class=MsoNormal><span lang=EN-US>/gate/world/daughters/name cylindricalPET</span></p><p class=MsoNormal><span lang=EN-US>/gate/world/daughters/insert cylinder</span></p><p class=MsoNormal><span lang=EN-US>/gate/cylindricalPET/setMaterial Water</span></p><p class=MsoNormal><span lang=EN-US>/gate/cylindricalPET/geometry/setRmax 100 mm</span></p><p class=MsoNormal><span lang=EN-US>/gate/cylindricalPET/geometry/setRmin 86 mm</span></p><p class=MsoNormal><span lang=EN-US>/gate/cylindricalPET/geometry/setHeight 18 mm</span></p><p class=MsoNormal><span lang=EN-US>/gate/cylindricalPET/vis/forceWireframe</span></p><p class=MsoNormal><span lang=EN-US>#/vis/viewer/zoom 3</span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;font-family:SimSun'>Simone<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;font-family:SimSun'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;font-family:SimSun'>Best and happy holidays.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;font-family:SimSun'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;font-family:SimSun'><o:p> </o:p></span></p></div></body></html>
