Hi,

My [quick-and-ugly] solution to this was to make ad hoc xslt worksheets. For example, I was running a series of simulations for a set of system sizes, so that there is a set of xml output files with different values of L. Then I first archive them all using the archivecat utility, and then run xslttransform ene_L.xsl archive.xml where ene_L.xsl is listed below. I'm sure there are more elegant and more generic solutions.

Cheers,

Zhenya

Hi,

The problem is that the standard scripts like extracttext or extractxmgr doesn't recognize the format of the dmrg output (at least in the version that I'm running). For example if I run a small dmrg simulation and I pretend to extract the energy value from the param.ask1.out.xml... This file looks like:

<EIGENSTATES number="2"> <EIGENSTATE number="0"> <SCALAR_AVERAGE name="Energy"><MEAN>-8.90438652987646</MEAN></SCALAR_AVERAGE> <SCALAR_AVERAGE name="Truncation error"><MEAN>1.127923664741207e-13</MEAN></SCALAR_AVERAGE> </EIGENSTATE> <EIGENSTATE number="1"> <SCALAR_AVERAGE name="Energy"><MEAN>-8.686440986186689</MEAN></SCALAR_AVERAGE> </EIGENSTATE> </EIGENSTATES>

As Mathias says there are the different averages associated with each eigenstate... If I use the standard plot.xml file I could not extract the energy from the <EIGENSTATES> block ... The question is: Should I modify the standard plot.xml file or it's needed changes in the alps scripts?

Thanks for your support!
