Dear abiniters,
I am trying to use GW wavefunctions(WFS) for further computing, I met two problems: 
 
1)Is it possible to extract GW WFS  as expansion of plane WFS, like the WFK file?
  
  In the code m_qparticles.f90, it seems GW WFS is an expansion of KS WFS in that K point(Am I right?).
  But I get confused of m_lda_to_qp(Old QP amplitude) and eigvec_qp (New QP amplitude),
 they are defined in line 64 in m_qparticls.f90,
  what is their difference and which one should I use? 
  
2)Is there a way to get interpolated GW wavefunctions, just like wannier90 for GW band energy?
 
I would appreciate if any suggestions.
And thank you in advance.
