Dear all,
I am trying to calculate phonon at Gamma for insulator material with 38 atoms /cell. I have got this error message:
Program PHONON    v.3.2.3  starts ...     Today is  7Oct2008 at 19: 3:42      Ultrasoft (Vanderbilt) Pseudopotentials %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%     from phq_readin : error #         1     reading inputph namelist %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%     stopping ...
I tried to figure out by checking several times, but it seems i am missing something...
thanks a lot for any help.
