Hi, Thanks for your help. I can run benchmark_spectra and benchmark_projections now. But the results obtained was different from the results showed in the manual. Is it allright, or something wrong somewhere? Followed are the messages: stolen:~/gate/gate_v3.0.0/benchmarks/benchmarkSPECT> ./benchmark_spectra gateSingles.dat Enter the lower energy threshold (MeV) 0.02 Lower energy threshold is 0.020000 MeV Enter the upper energy threshold (MeV) 0.19 Upper energy threshold is 0.190000 MeV Enter the number of energy windows 100 Energy range will be divided into 100 energy windows Enter the number of scattering volume (max is 10) 6 6 scattering volumes will be considered Enter the first four letters of the scattering volume number 1 shie Enter the first four letters of the scattering volume number 2 coll Enter the first four letters of the scattering volume number 3 comp Enter the first four letters of the scattering volume number 4 tabl Enter the first four letters of the scattering volume number 5 movs Enter the first four letters of the scattering volume number 6 phan The scattering volumes that will be considered are the following: shie coll comp tabl movs phan Beginning of processingEnd of processing   File fich_p correponds to the Unscattered spectrum File fich_c correponds to the photons which have scattered in the crystal File fich_t correponds to the total ernergy spectrum File fich_1 correspond to the photon whose last scatter interaction was  in the shie volume File fich_2 correspond to the photon whose last scatter interaction was  in the coll volume File fich_3 correspond to the photon whose last scatter interaction was  in the comp volume File fich_4 correspond to the photon whose last scatter interaction was  in the tabl volume File fich_5 correspond to the photon whose last scatter interaction was  in the movs volume File fich_6 correspond to the photon whose last scatter interaction was  in the phan volume File name fich_o1 corresponds to the first order scatter File name fich_o2 corresponds to the second order scatter File name fich_o3 corresponds to the third order scatter File name fich_o4 corresponds to the fourth order scatter File name fich_o5 corresponds to the scatter order greater than 4 Number of counts for the total energy spectrum = 36041 Number of counts for the Unscattered spectrum =12809 Number of counts for the total scatter spectrum =23232 Number of counts for the crystal scatter spectrum =2392 Number of counts for the shie scatter spectrum = 1 Number of counts for the coll scatter spectrum = 107 Number of counts for the comp scatter spectrum = 456 Number of counts for the tabl scatter spectrum = 1081 Number of counts for the movs scatter spectrum = 5123 Number of counts for the phan scatter spectrum = 0 Number of counts for the order1 scatter spectrum = 11176 Number of counts for the order2 scatter spectrum = 6120 Number of counts for the order3 scatter spectrum = 3004 Number of counts for the order4 scatter spectrum = 1500 Number of counts for scatter orders greater than 4 spectrum = 1432   ##########################################################################   Number of detected counts from 0.020 to 0.190 MeV : 36041 Unscattered events (percentage of total counts)= 35.54 Scatter in the crystal (percentage of total counts) = 6.64 Scatter in the shie volume (percentage of total scatter) = 0.00 Scatter in the coll volume (percentage of total scatter) = 0.30 Scatter in the comp volume (percentage of total scatter) = 1.27 Scatter in the tabl volume (percentage of total scatter) = 3.00 Scatter in the movs volume (percentage of total scatter) = 14.21 Scatter in the phan volume (percentage of total scatter) = 0.00 Scatter order1 (percentage of total scatter) = 48.11 Scatter order2 (percentage of total scatter) = 26.34 Scatter order3 (percentage of total scatter) = 12.93 Scatter order4 (percentage of total scatter) = 6.46 Scatter orders greater than 4 (percentage of total scatter) = 6.16   ########################################################################## For benchmark_projections; stolen:~/gate/gate_v3.0.0/benchmarks/benchmarkSPECT> ./benchmark_projections gateSingles.dat Enter the number of rows and columns of the images to be created 128 Image size is 128 x 128 Enter the lower energy threshold (MeV) 0.02 Lower energy threshold is 0.020000 MeV Enter the upper energy threshold (MeV) 0.19 Upper energy threshold is 0.190000 MeV Enter the size of the pixels (mm) 0.904 Pixels are 0.904000 mm x 0.904000 mm x Beginning of processing  End of processing   Number of detected events in the image of primary and scattered photons = 17619 Number of primary events in the image of primary photons= 6201 Number of scattered events  in the image of scattered photons = 11418   File Total correponds to the image of primary and scattered photons File Primary correponds to the image of primary photons File Scatter correponds to the image of scattered photons Appreciate your reply and help.

If you open up benchmark_spectra.c in a text editor and go to probably line 768 (but check to be sure) you should see that the line ends and then 769 is a new line. But it should be one continuous piece of code. But the compiler is "seeing" a new line of code, which of course is nonsense. If you just delete out any spacing between the two lines (but make sure to preserve the syntax) and recompile it should work. > > >    1.
