[Wannier] benzene example

[ans341 at mail.usask.ca]

Dear Wannier90 users,

I have been learning how to use Wannier90 program (version 1.1) and consequently
I have gone throught the examples provided with the program. What puzzles me is
the benzene example (/examples/example12/). I have managed to calculate the
valence states, but they are not what I expected. I was hoping to see a pi ring
around the ring but I only got this kind of MLWFs:

        xxx
       xxxxx                 xxxxx
   oo  xxxxx oo             xxxxxxx
   ooo_xxxxx_ooo           xxxxxxxxx              _______
   oo/ xxxxx \oo        xxo/oxxxxxo\oxx          /      o\    xxxx
   oo  xxxxx  oo      xxxo/oxxxxxxxo\oxxx       /      oo \  xxxxxx
3x /    xxx    \  6x  xxo/oxxxxxxxxxo\oxx   6x /      ooo  \xxxxxxxx
   \           /         \           /         \      ooo  /xxxxxxxx
    \         /           \         /           \      oo /  xxxxxx
     \_______/             \_______/             \______o/    xxxx

Could someone provide me with the correct results of the example 12 so that I
could try to reproduce them?

In addition, I would like to know if there is a way to use the PWscf wave
functions obtained from a parallel run (say, with 16 processors) with less
(say, 8) prosessors for pw2wannier.x? According to my short experience, it does
not work without something extra.

Thank you for your help!
