Now, When I run my macro file, every thing is fine loaded without any errors. The problem is by saving the data into root file. It means, the data is not writing into root file, although the simulation is running. The size of root file remains the same with increasing of the file size. When I have a look at the root file, the coincidence tree is empty. Did some one faced such problem before. I would be thankful if some body can help me with issue. Below you see the output of my simulation. Thanks in advance and regards, bassim Simulation output: [Core-0] Starting macro main1.mac [G4] Range Translator [G4] Range 0 : imageValue in [ 0.000e+00 , 0.000e+00 ] ---> material Air, visibility 0, coulour (0.000e+00,1.000e+00,0.000e+00,2.000e-01) [G4] Range 1 : imageValue in [ 5.000e+01 , 5.000e+01 ] ---> material Water, visibility 0, coulour (1.000e+00,0.000e+00,0.000e+00,2.000e-01) [G4] Range 2 : imageValue in [ 1.000e+02 , 1.000e+02 ] ---> material PMMA, visibility 0, coulour (1.961e-01,8.039e-01,1.961e-01,2.000e-01) [G4] Range 3 : imageValue in [ 2.500e+02 , 2.500e+02 ] ---> material PMMA, visibility 0, coulour (1.961e-01,8.039e-01,1.961e-01,2.000e-01) [G4] Range 4 : imageValue in [ 4.500e+02 , 4.500e+02 ] ---> material Glass, visibility 1, coulour (6.627e-01,6.627e-01,6.627e-01,2.000e-01) [G4] Range 5 : imageValue in [ 3.500e+02 , 3.500e+02 ] ---> material Lung, visibility 0, coulour (0.000e+00,0.000e+00,1.000e+00,0.000e+00) [G4] Range 6 : imageValue in [ 9.500e+02 , 9.500e+02 ] ---> material Water, visibility 0, coulour (1.000e+00,0.000e+00,0.000e+00,2.000e-01) [G4] Range 7 : imageValue in [ 1.050e+03 , 1.050e+03 ] ---> material Water, visibility 0, coulour (1.000e+00,0.000e+00,0.000e+00,2.000e-01) [G4] Range 8 : imageValue in [ 1.150e+03 , 1.150e+03 ] ---> material Water, visibility 0, coulour (1.000e+00,0.000e+00,0.000e+00,2.000e-01) [G4] Range 9 : imageValue in [ 1.250e+03 , 1.250e+03 ] ---> material Water, visibility 0, coulour (1.000e+00,0.000e+00,0.000e+00,2.000e-01) [G4] Range 10 : imageValue in [ 1.350e+03 , 1.350e+03 ] ---> material Water, visibility 0, coulour (1.000e+00,0.000e+00,0.000e+00,2.000e-01) [G4] Range 11 : imageValue in [ 1.450e+03 , 1.450e+03 ] ---> material Water, visibility 0, coulour (1.000e+00,0.000e+00,0.000e+00,2.000e-01) [G4] Header read from 'nema_phantom_downsampled.h33' [G4] Data file name 'nema_phantom_downsampled.i33' [G4] Nb of planes: 115 [G4] Nb of pixels per plane: 134 100 [G4] Pixel size: 1.988e+00 2.000e+00 [G4] Slice thickness: 1.500e+00 [G4] Matrix size: 2.664e+02 2.000e+02 [G4] Data type: UNSIGNED INTEGER [G4] [G4] nx ny nz: 134 100 115 [G4] dx dy dz: 1.988e+00 2.000e+00 1.500e+00 [G4] Nof Higher level 3 [G4] [G4] GATE object: 'digitizer/Coincidences' [G4] Is enabled?
