[Pw_forum] How to get the wannier_band.dat file

[yumin qian]

Dear Dmitry Korotin
  Thanks for your reply, it is very kind of you
  Can you tell me the right procedure, from a conventional LDA band
calculation to finally get the band dispersion  using wannier basis? I need
to compare how the wannier function will improve the result. Can it be
used in the case of  spin orbital coupling with LDA+U ?
