[Gate-users] how to generate an 3D image that can be used for the voxellized sources by GATE

[Kris Thielemans]

Hi

you can ask generate_image directly to use unsigned integers by adding a
few lines to the par file. something like

output file format:=Interfile
Interfile Output File Format Parameters:=
   ; optional to specify non-native byte-order
   ; byte order := littleendian
   ; type specification as in Interfile
   number format:=unsigned integer
   number of bytes per pixel:=2
   ; optional to fix the scale factor used when writing the data
   ; otherwise the maximum range of the output data will be used
   ; if it's an integer type
   ;scale_to_write_data:=1
End Interfile Output File Format Parameters:=
