<html><body><div>Hello, I have got a difficulty to run my PET macro on GPU. I have run it succesfully with the InterfileReader command and regularMatrix creator previously with this definition: ... /gate/world/daughters/name pacient /gate/world/daughters/insert regularMatrix /gate/pacient/geometry/insertReader interfile /gate/pacient/interfileReader/insertTranslator range /gate/pacient/interfileReader/rangeTranslator/readTable ATTMAP.dat /gate/pacient/interfileReader/readFile phantom.hdr ... Now I import the voxelized phantom as follows: ... /gate/world/daughters/name pacient /gate/world/daughters/insert ImageRegularParametrisedVolume /gate/pacient/geometry/setImage phantom_data/CT256.h33 /gate/pacient/geometry/setRangeToMaterialFile ATTMAP.dat ... ...but receive ... ### === G4UAtomicDeexcitation::InitialiseForNewRun() GateGPUEmisTomo.cc (l.359): pacient is not a GateRegularParameterized. GateGPUEmisTomoMessenger Update ... and simulation crashes. I have tried also ImageNestedParametrisedVolume and ImageRegionalizedVolume but the result is still the same. On CPU it works like a charm. 1.) Can anyone tell me what am I doing wrong and how to fix it? 2.) When I use ImageRegularParametrisedVolume, I always get this warning: ### WARNING ### setSkipEqualMaterials at false !! The Geant4 method is not safe since the release 9.5 - Need to be fixed ...what does it mean? Is it actually safe to use this volume creator? Does the command /gate/pacient/setSkipEqualMaterials 0/1 actually do something? Thank you very much in advance for answer. Best regards, Jiri Ters </div></body></html>
