Dear Dr. Gupta,

   As said by Prof. Blaha, you need "total forces" after each :FGLXXX value
and not "partial forces".
   As far as I remember, the "total forces" are written when we use the
"-fc" option in the run_lapw command, but I may be wrong (I used phonopy a
long time ago).
   Are you using the last version of Wien2k ?
   All the best,
                  Luis
