[Gate-users] Voxelized phantom and source

[Hanieh Jozi]

Dear Evi,
As I know, you should convert your image to a unit16 type(by MATLAB), because Gate can't read float type, it just knows unit16, and in your header file ,your data bytes order has to be littleendian.( outputs from gate are bigendian but that's not really important).
I hope that's help you.

I am using an .i33 image as a phantom (interfile format header .h33+raw image .i33). I have followed the user's guide instructions to define the voxelized phantom and source but I get this error when running the mac file:
