Dear Jianming Cai,

Please look at the ALPS 1.3 tools tutorial http://alps.comp-phys.org/mediawiki/index.php/Tutorials:ToolsHOWTO (especially Examples 3 and 4 in this wiki page) to learn how to write plot.xml for VECTOR_AVERAGE.

Best regards, Synge Todo

Dear Prof. Synge Todo,

I am a beginner to ALPS and I have run some toy model and got some output file from ALPS, as in the attached file.

And I hope to extract the value of spin correlation corresponding to the indexvalue for example (0)---(0), and spin structure factor

corresponding to the indexvalue of (0).

I was using extractext to extract the SCALAR_AVERAGE value such as Energy.

But for this kind of VECTOR_AVERAGE, I am not clear how to write the corresponding plot.xml, could you please give some help how can I extract these values?

Many thanks!

Have a nice weekend,

Yours sincerely,

Jianming
