Apparently, there is no reason. So I modify it, Thank you for your
remark.

Your inputs are 3D images (with a size for the third dimension equal to
1), so the output is a 4D image.
If you open your output with vv, you cannot see the last dimension
because when the 4th dimension is 1, the image is read like a 3D image.
You can see the new dimension displaying the mhd text file.
And the spacing of the 4th dimension is given by the option spacing.
