What I meant was that there is currently no tool in quantum-espresso
that can do Mulliken population.

You do a 2D contour plot, where the bond-direction lies on the plotting
plane. The cumbersome (but not difficult) part it to determine the
appropriate plane (origin + 2 spanning vectors). The recipe is as given
by Lorenzo in the previous email (i.e. via specifying the &PLOT namelist
Even if not all atoms of interests lie on the plotting plane this can be
still useful, moreover you may choose several plotting planes.

Yes precisely: the PDOS is a prerequisite for ILDOS. By PDOS you will
determine within which energy window to integrate. You may do several
