For "Error: Could not open header file 'hof3.i33'!" I guess it is just a typo in gate code, may should be data file not header file. Actually, a good practice in GATE is to copy all necessary files (e.g., GateMaterials.db, all macros, all header and data files) in running dir, and to check and modify respect dependency before running a job. Hope it is the case. Good lucky.

I am using the Interfile data distributed with GATE (found in $GATEHOME/examples/example_PHANTOM_SOURCE/Voxelized_Phantom_Source). When I try to read the interfile into GATE I get: PreInit> /gate/hof_brain/interfileReader/readFile ../hoffmann_data/hof3.h33 /gate/hof_brain/interfileReader/readFile ../hoffmann_data/hof3.h33  Header read from       '../hoffmann_data/hof3.h33'  Data file name         'hof3.i33'  Nb of planes:           55  Nb of pixels per plane: 128 128  Pixel size:             2.000e+00 2.000e+00  Slice thickness:        2.000e+00  Matrix size:            2.560e+02 2.560e+02  Data type:              UNSIGNED INTEGER Error: Could not open header file 'hof3.i33'! PreInit> I have looked at the hof3.i33 file (using matlab to read in the binary) and it seems completely uncorrupted. Does anyone know how to fix this problem? I wonder why it says could not open header file 'hof3.i33' when the .i33 file is in fact not the header (which is the .h33 file) and rather is the binary file? The .h33 file and the .i33 file are in the same directory and GATE seems to read the header file fine, so I don't think it is simply an access problem. I pasted my macro below (it is essentially the same as the GATE example). Thanks for any help. Daniel ############################################################################### #Phantom Macro.
