hi
dear Halima

The input for nscf would be more explicative, since the dos.x run is just a
post-processing of the data produced at the
pw.x level.

However, it seems to me that:
- you did not include "empty" bands, so you obtain zero DOS at E > 0
insert this nscf input file. i hope your problem will be solved.


&control

   prefix='Guallium'
