[QE-users] HP-code ERROR for PAW+ortho-atomic

[Mpayami]

Dear HP-code developers,

Hi.
I noticed that the hp.x posibbly has a small bug. When I use it with PAW potential and "ortho-atomic" projection, all the Chi components
are successfully calculated by at the end when starting "postprocessing", it issues lots of prints about distances between atoms
as shown in the following:

????????????????????????????????????????????????????????????????????
     Existing distances between couples of atoms:

     na=     1  nb=     1  dist=   0.000000
     na=     1  nb=     2  dist=   7.309222
     na=     1  nb=     3  dist=  10.336801
.....
.....
Missing chi element for: na=    96  nb=    96  dist=   0.000000


     Possible solutions:
     1. Relax better the structure (in order to have more accurate inter-atomic distances)
     2. Increase the value of the parameter dist_thr in the HP input,
        and re-run the postprocessing step by setting compute_hp=.true. in the HP input.

Any Comments is highly appreciated.
