Attached are two alternatives.

READING DATA in SPM:

hdr=spm_vol('filename')

img=spm_read_vols(hdr);

READING DATA in with openIMG:

[img hdr]=openIMG('filename')

==========

WRITING DATA in SPM:

hdr(1).fname='newfilename'

for ii=1:numel(hdr)

  hdr.n(1)=ii;

  spm_write_vol(hdr(1),img(:,:,:,ii))

end

WRITING DATA with writeIMG:

writeIMG(hdr,img,'newfilename')

The reason could be that spm_read_vols (plural) can read multiple volumes into a 4D matrix, whereas spm_write_vol can only write a single volume 3D or 2D.

You can write a wrapper easily to do that.

I am sure there might be good reason behind it not doing that
