[Pw_forum] Strange error out of scf calculation

[jibiaoli]

Dear All,


I try to do a scf calculation using pw.x, but got a strange error (below) that puzzled me the whole afternoon. Could anyone point out what wrong with the input file? Thanks a lot.
 
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     task #         0
     from  read_namelists  : error #        18
      bad line in namelist &control: "prefix = 'ZnS'，" (error could be in the previous line)
