Hello Paolo,
I mean ...............
When i do SCF calculation for Pnma structure, do not see all symmetries
present in system and find only 2 symmetries, which is not the case for
Pnma. Also message displays symmetries with points 0.5 0.5 0.5
ignored.................So i dont understand with this message, and only 2
symmetries, calculations are correct or not......................and getting
less symmetry points is a real problem with my calculation or something
else.
Please let me know where is problem,
