Your k point is wrong, for one thing. Maybe you're not looking at a band underneath the light line.
Look at the line-defect.ctl example file included with MPB. Alternatively, you may find it easier to rearrange things into an orthogonal supercell.

Attached is the CTL file. _______________________________________________ mpb-discuss mailing list [email protected] http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/mpb-discuss
