[Wannier] how do you determine which Wannier orbital corresponds to which projection?

[Robert Collyer]

All,
I know from a previous question posted to this list that you determine 
where each Wannier orbital is located in the Hamiltonian via the 
case_centres.xyz file.  But, how do you determine which orbital is 
which, e.g. d_z^2, etc.?  Is this even possible with the amount of 
mixing going on in the unitary transform?

Thanks,
Rob Collyer
