The documentation is here:


You'd use that from within a Python script or interactive session, as in:

In [4]: img = nib.load('a_4d_image.nii')
In [5]: images = nib.four_to_three(img)
In [6]: for i, img_3d in enumerate(images):
   ...:     nib.save(img_3d, 'a_3d_image_{:03d}.nii'.format(i))

You could also use the program `nipy_4d_to_3d` from NiPy.
