I have mainly 3 questions: </div>(1) In examples/example_PHANTOM_SOURCE/Voxelized_Phantom_Source/ why the data file brain_phantom.i33 is brain_phantom.md5?What is the meaning of md5? </div>(2) In the same folder, when I try to run mainMacro.mac, it starts normally but than suddenly stops and I receive the message "GateVImageVolume.cc (l.570): I find R=25907 in the image, while range stop at 15" </div>What's wrong? </div>(3) I try to run the same file but with my voxelized source and I receive the following error: GateSourceVoxelImageReader::ReadFile : fileName: ', assuming default BIGENDIAN'LITTLEENDIAN 'nrecognised type name 'unsigned integer ', assuming default BIGENDIAN'BIGENDIAN 'nrecognised type name 'unsigned integer Header read from 'PET_PVC-MTC.h33' Data file name 'PET_PVC-MTC.i33' Nb of planes: 176 Nb of pixels per plane: 448 512 Pixel size: 5.273e-01 5.273e-01 Slice thickness: 2.086e+00 Matrix size: 2.363e+02 2.700e+02 Data type: Data byte order: BIGENDIAN **** Error: Volume does not exist **** Ignoring confine condition </div>and after some lines: *** Break *** segmentation violation </div><div> My interfile is: !INTERFILE := !imaging modality :=nucmed !originating system :=ImageJ !version of keys :=3.3 !date of keys :=1992:01:01 !conversion program :=ImageJ !program author :=J.
