thank you for responding 
but i want the figure probability versus P-N vector angle and g_sgangle dont give this output .just g_angle give this output

g_sgangle with the -z option (assuming the bilayer is in the x-y plane) should do this.  The index group can contain two atoms (or a suitable multiple of two defining all the P and N atoms).
