[Wien] answer to write_win mistake

Dear Ge,

As far as I can judge from your input files the number of k-points in case.win is 317 and not 512=8*8*8 as it should be.

I guess that something went wrong with the symmetry operations. Be sure to have a case.ksym file with just 1 symmetry operation that is the identity
1 0 0
0 1 0
0 0 1

and then call x kgen -so . In the dialogs, say 8 8 8 to define your k-mesh. Before exiting kgen should tell you it created 512 k points.

In the newest version of the inferface(0.94) the klist file write_win looks for, is called case.klist_w90, so be sure to copy the case.klist by hand if you are not using the initialization script init_w2w.

Best,
Philipp

Dear Wien2k users,

Recently,I begin learn how to use wien2wannier, but there are some problems I met.
when I run wannier90.x -pp srvo3 after write_win, an error is shown as, 'wannier90 error: examine the output/error file for details', but when I copy debug.win in templates file to srvo3.win, it can run normally. The case.werr and case.win are shown as following:

  THE case.werr is

  Wannier90: Execution started on 10Jul2011 at 17:30:36
  Exiting.......
  Error: Wrong number of lines in block kpoints

AND THE case.win is
