Dear Prof. Oleg
Sorry to interrupt you.
Earlier I was looking for the wrong file.
My case.klist has 40 k-points and thus #KP also varies upto 40.
>From my eigenvalue file, my VBM lies on band index=38 (XX)
row number   KP(YY)  ENE
653            1.08800    -0.04699
So according to your hint, I should look for #KP 653 and then index number
38.
But I have #KP upto 40.
You also mentioned occupancy, but I could not understand it.

Could you please correct me?

Thank you in advance.
Regards
Bhamu
