Dear all users,  <BR>
<BR>
I try to test electron-phonon calculation via example03 (metal Al) in package PHonon5.0.1 by using espresso.5.0.1.  <BR>
<BR>
Two SCF calculations and ph.x are smoothly performed. Al.dyn* and a2Fq2r.* files were obtained.  <BR>
<BR>
Then i run q2r.x, but fail when read a2Fq2r.* files. The error is as follows. <BR>
<BR>
      q-space grid ok, #points =   64 <BR>
<BR>
      fft-check success (sum of imaginary terms < 10^-12) <BR>
<BR>
   Preparing gamma for a2F <BR>
<BR>
<BR>
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% <BR>
     Error in routine init (1): <BR>
      nc already filled: wrong q grid or wrong nr <BR>
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% <BR>
<BR>
Any comments are welcome. Thanks a lot.  <BR>
