--out-4d OUT_4D

False if you want to ignore differences in affines between the 3D images, True if you want to raise an error for significant differences (default is True)

nipy_3dto4d will take a series of 3D nifti images in any format readable by nibabel and concatenate them into a 4D image, and write the image with format guessed from the output image filename. You can set the filename with the ``--out-4d`` parameter, or we make a filename from the input names.
