Dear Soumyadeep,
you can have a decent idea by doing a projected wavefunctions analysis 
(if you are using Quantum-ESPRESSO with projwfc.x), i.e. plotting the 
density of states projected on the atomic orbitals. This takes time and 
a bit of patience, but it will help you understand the system you're 
studying much better.

I'm quite sure that other ab-initio softwares have similar tools

hope this helps
