Hi, all,

        The corresponding DOS and integrated DOS have been generated after the claculation of total DOS, but  i just little bit more confused about the result, the numeric values of DOS is very large while the intergrated DOS is reasonable. To my way of thinking, the DOS shows the numbers of states which can be occupied by the electrons along the engery axis, so  the integral value of DOS should equal to the number of valence electrons for a given model when the integral interval was set between the bottom of valance-band and the zero engrgy (fermi energy) , obviously this is impossible base on the data of DOS generated by abinit, the integral value is much larger than integrated DOS....... how does this DOS generated?
   Thanks in advance.
