Dear Matthieu, Thanks very much for your quick reply. I indeed used the HGH psp file. I used the HGH psp file in the abinit-5.7.3.tar.gz package. And I am doubting whether there are problems when I compile the abinit programme. I have correctly installed ifort, lapack and blas package before installing abinit. I can do calculation without spin-orbit correctly. Then what is wrong? Best wishes.
