[Insight-users] Inputs do not pccupy the same physical space!

[Hui Tang - TNW]

Dear ITK user,



I got this error



terminate called after throwing an instance of 'itk::ExceptionObject'
  what():  /home/htang/Programs/ITK4/ITK/Modules/Core/Common/include/itkImageToImageFilter.hxx:253:
itk::ERROR: xxxxxxxxxxxtImageFilter(0x166f080): Inputs do not occupy the same physical space!
InputImage Origin: [0.117188, 12.0703, 104.7], InputImage1 Origin: [0.117188, 12.0703, 104.7]

when I read one image.



I did

software1.exe -i input.mhd -o output1.mhd

software2.exe -m output1.mhd -n input2.mhd -o output2.mhd



software1 is built on ITK3

software2 is built on ITK4



If I replace output1.mhd with  input2.mhd , software 2 does not give any error.

(do  software2.exe -m input2.mhd -n input2.mhd -o output2.mhd)



The weird thing is if I visually check output1.mhd and  inpput2.mhd, they do not look different, but their position of origion  differs slightly.



 the origins are:

5.000000000005e-07

11.9531125

104.4



and



4.99188999997235e-07

11.9531254992

104.400004148079



I would appreciate you if you can help me to solve this problem, thanks a lot!!!
