INP file do not contain demand pattern

[lookforhan]

I use the epanet to open an INP file which does not contain Demands Pattern.
`error in epanet/saveBinInpFile (line 4966)
fprintf(f,'\n%s%s%f%s%s',obj.BinNodeNameID{u},sps,obj.BinNodeBaseDemands(u),sps,obj.BinPatternNameID{1});

error in epanet (line 446)
obj.saveBinInpFile;

error in epanet_pdd (line 77)
obj.Epanet = epanet(varargin{1},'BIN');`
