Dear Dan If I remember well, the rrkj ultrasoft pseudization is built on a preliminary norm-conserving pseudization, which can be rrkj (tm=false) or troullier-martins (tm=true). The pp type is enforced by pseudotype=2 (NC) or pseudotype=3 (US or PAW) HTH Giuseppe Dan Gil ha scritto:

Dear M. Inukai, I would like to add a small note to the very comprehensive response of Iurii and Oscar regarding the "pseudo_hermitian" option: In my experience if the code fails with this option set to .TRUE. it might mean that there are some problems with your system or parameters (

Dear M. Inukai, 1. num_eign = number of eigenstates (excitations) which will be computed. This parameter must be chosen based on how large energy range for the spectrum the user is interested in. The bigger the energy range, the larger num_eign is. A priori it is not possible to guess this
