distinction between hole and electron states is not clear

I ran a 2 band model in a dome structure with a wetting layer and it appears that I got 8 valence band states but it was NOT clear.   How can I just ask for conduction band states?   Please advise.

    When you choose the number of eigenvalues, half of them are found in the valence band region and other half in the conduction band region. I will add the feature to just calculate either conduction band/valence band states.

    Now you can set the number of eigenvalues for CB and VB independently.

    Thank you for your question.   

    Can you please share more details on your simulation with me, and I will try to understand your question in more detail.   Indeed Hole and Electron states are, I believe displayed in the same color format.   That is possibly something that can be modified in the visualization.   As of now there is just a stack of eigenvectors (eigenstates) that are sorted by energy.   The electron ground state should be easy to spot.  It should be s-like.    The hole ground state could already look deformed or strange.   But basically roughtly s-like.
