In the mean time, I will try to use ALPS 2.0. Thank you.

Can you send your output files? The problem is probably that mu is not
just a number. You might also look into using ALPS 2 instead which has
much better plotting and evaluation tools.

Dear ALPS community,
    I met a trouble for extracting the calculated results from the

XML output files. My setting is the following:
plot2.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<plot name="Stiffness versus disorder for three-dimesnional
HardcoreBoson
models">
 <legend show="true"/>
 <xaxis label="Disorder" type="PARAMETER" name="mu"/>
 <yaxis label="Stiffness"  type="SCALAR_AVERAGE"/>
 <set label="Inhomogeneous simple cubic lattice"/>
</plot>
and my "input" file is
LATTICE_LIBRARY="lattices.xml";
LATTICE="inhomogeneous simple cubic lattice";
L=5;
MODEL_LIBRARY="models.xml";
MODEL="hardcore boson";
t = 1.0;
T = 0.1;
delta=10.0;
SWEEPS=500000;
THERMALIZATION=10000;
EPSILON=0.25;
{ DISORDERSEED = 34275; mu=delta*2*(random()-0.5); }
{ DISORDERSEED = 49802; mu=delta*2*(random()-0.5); }
{ DISORDERSEED = 82529; mu=delta*2*(random()-0.5); }
{ DISORDERSEED = 13564; mu=delta*2*(random()-0.5); }
{ DISORDERSEED = 65897; mu=delta*2*(random()-0.5); }.
When I typed the command "extracttext plot2.xml input.task*.out.xml",
the
following thing happend:
plot2.xml:4: parser error : XML declaration allowed only at the start of
the document
<?xml version="1.0" encoding="UTF-8"?>
^

unable to parse plot2.xml
/tmp/archive2plot3652.xsl:1: parser error : Document is empty

/tmp/plot3652:1: parser error : Document is empty
^
/tmp/plot3652:1: parser error : Start tag expected, '<' not found

I don't know what is going on here, could you help me figure it out?
Thank
you in advance!

Dear Francesco,
The source code needs to be modified, but it is very easy to write such a
code. Anyone in my group at ETH can teach you how to do that. I'm on
vacation and without good internet this week but we can meet next week, or
you can ask others on my group whether they can help you. Writing a local
update code for your model should not take more than half a day at the
most.

Dear ALPS community,
could you please let me know about the possibility of including
Dzyaloshinskii-Moriya in spinmc, possibly through the presence of an
off-diagonal exchange coupling constant?
Is it necessary to modify the source code for such a case, or can I
manage it in some other way not explicitly mentioned in the ALPS
tutorial?
Best wishes
Francesco
