[Neuroimaging] affine issue (?)

[Christophe Pallier]

Hello,

I have an nii image (a contrast computed by SPM, in the MNI space),
which, according to SPM, has the following affine:


>> V.mat
2   0   0    -74
0   2   0   -108
0   0   2    -66
0   0   0    1


However, the same image loaded with nibabel yields a different affine:
[[   2.            0.            0.          -72.00000763]
 [   0.            2.            0.         -106.        ]
 [   0.            0.            2.          -64.        ]
 [   0.            0.            0.            1.        ]]

Any hint?
