<div dir="ltr"><div><div>Hello, Gate users! </div>I'd like to simulate CT system. For this reason I've downloaded an example tp_CT_solution.tar.gz which can be downloaded on the next link: <a href="http://www.opengatecollaboration.org/Materials2015/PracticalExercises2015/CT">http://www.opengatecollaboration.org/Materials2015/PracticalExercises2015/CT</a> . </div><div> </div><div>I've untared this file and I'm trying to run the main macros simu_ct.mac. But something goes wrong. I use Ubuntu 14.04 LTS, root v5.34/34, geant4-09-06-patch-03, gate_v7.0. When I type: Gate simu_ct.mac </div><div>the next lines appear in the terminal: g4user@g4user:~/My_programs/gate_v7.0/examples/tp_CT_solution/solution$ Gate simu_ct.mac [G4] [G4] ************************************************************* [G4] Geant4 version Name: geant4-09-06-patch-03 (14-March-2014) [G4] Copyright : Geant4 Collaboration [G4] Reference : NIM A 506 (2003), 250-303 [G4] WWW : <a href="http://cern.ch/geant4">http://cern.ch/geant4</a> [G4] ************************************************************* [G4] [Core-0] Initialization of geometry [Core-0] Initialization of physics [Physic-0] WARNING: manual physic lists are being deprecated.
