Hi, I have successfully installed ALSP 1.3.5 on Kubuntu 10.04. I did not get any error nether during installation nor during "make test". When I try to follow test case for Monte Carlo simulation parm2a and performed simulation. Then I could not generate xmgr output file with extractxmgr plot.xml parm2a.task*.out.xml > plot2a.xmgr It generates the following errors: exit: 19: Illegal number: -1 exit: 19: Illegal number: -1 exit: 19: Illegal number: -1 Would you please help me to understand what is wrong? I have just followed the instruction according to web page: http://alps.comp-phys.org/mediawiki/index.php/Tutorial:ClassicalMCSimulation... My plot.xml file content is as in the web site ++++++++++++++++ <?xml version="1.0" encoding="UTF-8"?> <plot name="Susceptibility versus temperature for one-dimensional Heisenberg models"> <legend show="true"/> <xaxis label="Temperature" type="PARAMETER" name="T"/> <yaxis label="Susceptibility" type="SCALAR_AVERAGE"/> <set label="One-dimensional chain"/> </plot> +++++++++++++++ I got the same error with other extract* tools. With best regards, Ruben
