You either typed the command in wrong, or did something else wrong, the "-f
1" does not belong.  In addition, "-NI" should not be used when you change
mode (e.g. GGA to HF). It may be that your calculation has converged, but
due to incorrect options you have told it to converge to "zero" energy
tolerance (as a guess).

Type in "Check-mixing_lapw" in the relevant directory and paste the result
into an email response (to everyone).
