 Respected  Users,<br>
<br>
<br>
 I'm getting the following error during the electron phonon calculation.<br>
<br>
 electron-phonon interaction  ...<br>
<br>
<br>
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%<br>
     from elphsum : error #         3<br>
     q is not a vector in the dense grid<br>
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%<br>
<br>
     stopping ...<br>
<br>
<br>
 Could anyone tell me what might be the possible reason of this error???<br>
<br>
 Should I use  16x16x16 MP grid for  q points instead of 4x4x4 grids  to<br>
 get rid of the above error????<br>
<br>
  Regards,<br>
