      Hi, Matthias
this is the custom lattice I am using:
-------------------------------------my_lattices.xml----------------------------------------------------------------------
<LATTICES>
<LATTICE name="chain lattice" dimension="1">
  <PARAMETER name="a" default="1"/>
  <BASIS><VECTOR>a</VECTOR></BASIS>
  <RECIPROCALBASIS><VECTOR>2*pi/a</VECTOR></RECIPROCALBASIS>
</LATTICE>
<UNITCELL name="fermion" dimension="1">
  <VERTEX type="0"/>
  <VERTEX type="1"/>
  <EDGE type="0"><SOURCE vertex="1" offset="0"/><TARGET vertex="1"
offset="1"/></EDGE>
  <EDGE type="1"><SOURCE vertex="1" offset="0"/><TARGET vertex="2"
offset="0"/></EDGE>
</UNITCELL>
<LATTICEGRAPH name = "chain lattice">
  <FINITELATTICE>
    <LATTICE ref="chain lattice"/>
    <PARAMETER name="L" default="4"/>
    <EXTENT size="L"/>
    <BOUNDARY type="periodic"/>
  </FINITELATTICE>
  <UNITCELL ref="fermion"/>
</LATTICEGRAPH>
</LATTICES>

Hi, ALPS developers and users
When I did DMRG with the "Kondo lattice" model in ALPS lib, the computer
returned error:
"Site basis for type 2 not found and no default exists."
I do not know whether it is the problem of my code or the ALPS model
itself, so dear developer, is this "Kondo lattice" model in your lib being
tested by DMRG? If it is not, can you test it and tell my whether it works?
(take you five minutes most) Thus, I can make up my mind whether I should
find other way of coding or continue debuging this code which returns
problem. This is really a big help!
