Subject: ABOUT POINT GROUP OF (Pnma) STRUCTURE
To: PWSCF Forum <pw_forum at pwscf.org>


i have given all my files regarding the problem.
why i am not finding the correct mode symmetry of pnma structure of Sb2Se3
compound by calculating the phonon at gamma point.as it is a orthorhombic
structure  so it should show D2h_(mmm) but it is showing as C2h(2/m)
so whether i am doing anything wrong in my input......
