Hi Vijay, I don't think any of us quite understand what your goal is, and it is therefore difficult to help. I assumed that you are trying to plot the band structure of some compound with labelled k-points and a larger range of energies than usual. I hope it helps. There are a few things you need to consider when using elk-bands. 1) Does the elk simulation have enough bands to cover the energy range you care about. As Michael mentioned, this is controlled by nempty. The default is probably ok for...
