i donot think abinit code could handle  the work you described. 
if you wanna examine the bands around the fermi  level or bands edges, i think you can easily
change the energy range in plotting.

hi Lan,
thanks for your reply, but i just want to know how to calculate the bands within 1 or 2 eV around the fermi level, i mean that other band could be neglect.

certainly 'nband' can specify the numbers of bands i want to calculate,but i found that abinit generates eigenvalues in a order from the low to high enery according to the corresponding valence states. for instance, if the valence states that abinit considers is 2d3s3p and the 'naband' was set to be 1,then just 1 band of 2d state will be calculated because of the 2d state locates at the lowest energy, in my question, how to set parameters so that abinit can just calculates the band which locates at the higher energy levels in a single band structure calculation?
