Hi，if i get a "**.nc" file ,and i want to get the date of bandstructure, how can i export txt file without GUI, just in python ?
Thank you!

The easiest option is to use "nlprint". If you want to format the data differently, you can query the Bandstructure object for the energies, route, and kpoints (see the reference manual for details) and print them yourself.
