Hi, All,

 I have reproduced a well-defined band structure for 4-atom CoO by using 10
WF. After that, I tried to export several WFs by using several commands as
follows:

Step 1. write_inwplot
    This command generate a case.inwplot:
    3D ORTHO                                    # mode
O(RTHOGONAL)|N(ON-ORTHOGONAL)
    -1 -1 -1 1                                  # x,y,z,div of origin
   1 -1 -1 1                                   #              x-end
   -1 1 -1 1                                   #              y-end
   -1 -1 1 1                                   #              z-end
   30 30 30 0 0 0                              # grid points and echo
increments
  NO                                          # DEP(HASING)|NO
(POST-PROCESSING)
  WAN ANG LARGE                               # switch ANG|ATU|AU
LARGE|SMALL
   1 1

Step 2.  x wplot -wf 1 -up

Step 3. x wplot -wf 1 -dn

According to the User guide, these three commands should  create
case*.psink and case*.psiarg " files, but I found there was no data within
these files. Could you show me how to export WF for spin-polarized cases?

Best
Fang
