<br>
it seems you have k-point index=38, band index=653. To be on a safe side, I would look for band ranges (":BANXXX") in case.scf (last iteration). The occupancies are written down in the same table. If you have questions about interpretation of :BANXXX, it will be better if you list this section for your SCF file.<br>
<br>
Thanks<br>
Oleg<br>

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

Oh, sorry about the misunderstanding. In your previous correspondence it sounded as you had a confusion about which klist file is used.<br>
<br>
> In my case the CBM/CMB is at N-point which is located at 622 row number in case.klist_band. But I have only 20 K-points in my case.klist and thus the total KP in mstar output file is also 20.<br>
<br>
To get band edges, I would check an eigenvalues file to identify band number XX, k point number YY, occupancy. Then look for a line "# KP: YY" and band XX below that in the output of mstar.<br>
<br>
I hope it answers the question<br>
Oleg<br>
