Hi, > but all output files are having namelist error it's because bands.x needs a different input file which starts with &bands but here you are using something else.
> error MPI ABORT process 0 this error probably stems from the previous error > I dont know how to introduce bands.x correctly in the run_example you don't have to... just go to PP/examples/example01 (as pointed out by Ajit) and run it. It will calculate the band structure and charge density which you can visualize using evince (or any other post script viewer). > if it is very trivial it should be if path to your binary and pseudo files are properly set (see environment_variables) Surender
