Total structure factor + total charge density +pressure +chain dimensions

I did simulation for PDMS as information in attached file and I got relation between Pair separation distance and g (r). but I need relation between structure factor H(k) and K[A] Fig( 2) , density vs. r [A] fig (5), and the value of P (atm) , Rg (radius of gyration) , Ree end to end distance) as in table 3.
