nebmake.pl works only orthorhombic cell?
Posted: Tue Feb 28, 2012 7:11 am
i am wondering if the standard nebscripts works only for orthorhombic supercell ( three supcell vector orthorhombic perpendicular to each other)?
I had a great experience using, for example, nebmake.pl to do calculations for orthorhombic supercell , eg

but strange behaviors start to come up when I move to a rhombic unit cell ( |a|=|b|, a, b angle=60 degree, c perpendicular to ab plane)
