You need to manually parse the output file in ALPS 1.3. It is much easier in ALPS 2.0, and thus I recommend switching to ALPS 2.

Hello
I am currently using ALPS 1.3.
To be more specific, I am currently looking at hardcore bosons on a 2D triangular lattice and I am interested in extracting the structure factor for the wave vector (4*pi/3, 0), which of course corresponds to the 1/3 filling case.

This is easiest in ALPS 2,0 using the Python tools. Are you using ALPS 1.3 or 2.0?

Hi all
I was wondering how can I extract a single part of a vector average,
for
example a single value from the Structure Factor. I am looking
along the
lines of how would I write the xml file to get the results out.
Below I
have a simple plot file for Magnetization. How could I change it to
get
out one part of a vector average, such as from the structure factor?
<?xml version="1.0" encoding="UTF-8"?>
<plot name="Magnetization Density">
<legend show="true"/> <xaxis label="chemical potential" type="PARAMETER" name="mu"/> <yaxis label="Magnetization Density" type="SCALAR_AVERAGE"/>
<set label="2D triangular lattice"/>
</plot>
In advance thank you for the help.
