I don't know how to set the parameter :NEDOS .And is there some keys to set the NEDOS for the different systems ,for example ,the molecular ,the periodical system ,the conductor ,semiconductor ,insutor and the bulk ,and the surface ?

NEDOS is "just" the number of energy points in your density of states file in the end. If you want a finer grid, increase this number to what you want. Note that for a real fine DOS, you also have to play with the number of k-points and the smearing factor.
