Dear N. Hasan
pw.x input describes all flags, so you can refer to the link below to
understand differences between Crysta_b and Tpiba_b.
Briefly Tipba_b defines K points in units of 2 pi/a while Crystal_b uses
crystal coordinates to define them so actually K_points are not exactly the
For 2nd Question use xcrysden package to plot K_points in irreducible
brillouin zone (IBZ).
