[Pw_forum] charge is wrong and system is non-metallic

[Jonas Baltrusaitis]

My crystal get's recognized as metallic even though it's a pure insulator (urea) and calculations abort with charge is wrong message. I want to use this simple molecule as a compound containing O,N,H,C for threshold and pseudopotential testing

    prefix='urea_test1',
    pseudo_dir='/share/apps/espresso-4.0.4/pseudo/',
