a question about Wannier90 function

Dear all, i am try to do a wannier90 calculation with abinit8.10.3 using hgh potential and with SOC effect(nspinor=2). Attached are .in and .win files. The data set 1 is OK. But when I run the data set 2, I got an error, the message in the .werr file says "param_get_projections: spin is defined but ...

Fat band calculation with HGH

Dear All,
Is it possible to do a fat band calculation with HGH pseudopotential? like the attached file.
I found PAW is ok for this purpose. But I have to use HGH in order to simulate alloy with mixalch.
Thanks in advance.

about mbjlda calculation

Hello all,
I am doing a calculation with mbjlda method on a slab model, but after several hundred scf cycles, the energy is still not converged. Are there any skill to accelerate the converge process? Thanks.
