How to calculate electron overlap population using Mulliken charges in DMol3?

I have run Energy calculation using mulliken charges in population analysis, specifying charge matrix and keeping the symmetry off. But in the result obtained I was unable to find any information in regards to either the bond order based on Mulliken charges and the overlap population. I have further, imported the the mulliken charge (charge matrix) within the structure, but could find no addition information except the atomic charges. I have tried to import, total electron density as well to see if any additional information is available, but could not find anything new. 

Please kindly help me to find a solution to this problem.
