Dear Kaveh Edalt,

Please apply the patch attached at the end of this email to tool/lattice-preview.in and rebuild alps, or edit directly the very last line in /opt/alps/bin/lattice-preview as

python "$SCRIPTDIR/preview.py" "$@" < /dev/null &

then start lattice-preview, e.g.

lattice-preview LATTICE="square lattice" L=8

Note that you need wxPython and vtk modules for lattice-preview to work correctly.

Best, Synge

Dear All

I want to make a new lattice, but before serious calculation, I like to see the lattice.

I searched in the alps mailing list and I found that probably "lattice-preview" should be a tool for visualization of lattices in ALPS. But I have two problem: first, when simply I type "lattice-preview" in the terminal I receive the following error:

/opt/alps/bin/lattice-preview: 30: /opt/alps/lib/python/alps/preview.py: Permission denied

Is there anyone to know why I receive the error?

second, If we suppose the "lattice-preview" works well, what is the input file for this program?

thanks in advanced
