Hi, <br>When using LSDA+U(AMF), do I have to turn on spin-orbit interaction? On page 87 of the last userguid, it says that it is necessary to use LDA+U in combination with the spin-obital coupling. In addition, when doing LDA+U calculation for a system with inversion symmetry, is it necessary to turn on complex calculation?<br>
