Probability density maps

Hi,

Is it possible to create probability density maps of cation-anion systems in Materials Studio such as the one in
Costa, Luciano T., and Mauro CC Ribeiro. "Molecular dynamics simulation of polymer electrolytes based on poly (ethylene oxide) and ionic liquids. I. Structural properties." The Journal of chemical physics 124.18 (2006): 184902 (please see fig. 6, 7 & 8).

Thank you,
Ishwar
