[Pw_forum] MoS2 valence bands

Hello all,
I am trying to calculate the electronic band structure for monolayer MoS2
using quantum espresso.Mo and S both have 6 valence electrons, a total of
18 valence electrons in the unit cell. Hence I expect to have 9 valence
bands but I see that I get 13 valence bands. I have not considered spin
orbit interaction. Is it something I am assuming wrong ? Kindly let me know.

thank you
