[Pw_forum] LDA+U and noncolin lspinorb : hub file not written?

Dear all,

sorry for the late response; the problem seems to be that I have specified
only one k-point. The system complains about gamma tricks but not about a
single k point (1 1 1 0 0 0), when I double the k points the files are
properly written!

Thanks for your help!

Chris
