Hello, all,
    I tried to use 'cut3d' to write out wavefunctions u(r) for every band(for example, only one k point), then calculate the charge density on real space by using n(r)=\sum_{bands}u(r)^{*}u(r). But I found out the calculated n(r) is not exactly the same as charge density given out from _DEN(cut3d). Although they are on the same mesh points. Could anyone comment on this?
   Is it possible that n(r), and u(r) are written out from different iteration steps?
   Thanks a lot.
-Best,
Min
