Hi friends.I am learning working with alps so I test the codes that is written in website for classic monte carlo simulation.I wrote those codes on my terminal but when I arrive to codes below:

extracttext plot.xml parm2a.task*.out.xml

extractxmgr plot.xml parm2a.task*.out.xml > plot2a.xmgr 
xmgrace plot2a.xmgr

it gives error and in my terminal it said that

/opt/alps/bin/xslttransform: 16: exit: Illegal number: -1

/opt/alps/bin/xslttransform: 16: exit: Illegal number: -1

/opt/alps/bin/xslttransform: 16: exit: Illegal number: -1

so what shoul i do?

also how can I install xmgrace for the above code?
