Dear All
I'm new to ABINIT.
Can any one tell me the basics to determine the band structure calculation for a required material.
I'm using windows 5.6.4 binary.

Hi,
I would advice you to make the tutorials 1 to 4. It is quite self-explanatory and you will learn a lot about the basics of abinit. Specifically, you will see how to determine a band structure in tutorial 3 (but do tutorial 1 and 2 first if you havent).

Thanks David
I have modified the band structure program of Silicon to find the band structure for another one.
How to visualize the electronic structure from the abinit.out file

The _EIG file (generated by default using the prteig 1 option) has the energies as functions of k points. You can extract what you need from there. There is also a little utility in the abinit install directory, under util/users, called AbinitBandStructureMaker.py. You have to run it twice, first on your output file so it can make a "database" of energies, and then on the database so it can make a file readable by the xmgrace plotting program.

The ab*.py script isn't a program to be compiled, it's a python script that has to be interpreted by a python interpreter. So you need to have python running on your system and then execute something like "python ab*.py <your output file name>".

Yes, see the various comprehensive reviews by Gonze et al., for example Computer Physics Communications, 40th Anniversary Issue, 180, 2582 (2009).
