MESH = 8 8 8
MESH numbers give uniform meshes (8) in each axis.
GAMMA_CENTER = .TRUE.
Instead of employing the Monkhorst-Pack scheme for the mesh sampling, \Gamma center mesh is used. The default value is .FALSE.
DOS = .TRUE.
This tag enables to calculate DOS. This tag is automatically set when PDOS tag or -p option.
DOS_RANGE = 0 40 0.1
Total and partial density of states are drawn with some parameters. The example makes DOS be calculated from frequency=0 to 40 with 0.1 pitch.
FMIN, FMAX, and FPITCH can be alternatively used to specify the minimum and maximum frequencies (the first and second values).
PDOS = 1 2, 3 4 5 6
These numbers are those in the primitive cell. , separates the atom sets. In this example, atom 1 and 2 are summarized as one curve and atom 3, 4, 5, and, 6 are summarized as another curve.

主要的设置差不多就这些,其他的可以参考链接,官网给出的解释。
