Hallo Khader,
it's on my webpage -- google me as Viviani Ulm and follow the links.

> As a follow-up to this important Question or Comment:

> I wonder if there is a detailed Binary or digital atlas in

> The universal availability of such labelled Blood Atlas in the

>
> This "wished" atlas to be wriiten in MNI or analyze formats should
> be loadable in SPM toolboxes and MRIcro/N-GL family to make it
