[Gate-users] Voxelized Phantom uint32

Hello Gate users ,

I am trying to use a voxelized phantom and a voxelized source for a
simulation. However, I get the following error message when I am compiling
the script,
GateVImageVolume.cc (l.734):  I find R=2.7172e+09 in the image, while range
start at -1 .

I am using an Xcat phantom, whose values I have converted to 32-bit
unsigned integer  using a linear equation.
The h.33 header I am using is :
!INTERFILE :=
!matrix size [1] := 256
!matrix size [2] := 256
!name of data file := data/Xcat_650_750_0.1250_uint32.bin
!number format := unsigned integer
!number of bytes per pixel := 4
!imagedata byte order := LITTLEENDIAN
scaling factor (mm/pixel) [1] := +1.250000e-00
scaling factor (mm/pixel) [2] := +1.250000e-00
!total number of images := 101
!number of slices := 101
slice thickness (pixels) := +1.250000e-00
!END OF INTERFILE :=


Any tips about what is going wrong?
