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!
