Charge transfer analysis

I am working on adsorption of gas on Al doped MoS2 monolayer. I try to calculate the chrage transfer (Q) for the adsorbed system. In an article I have find that Q=Qa-Qb. Where Qa denotes the charge of the isolate (doped atom or gas molecule) before the change and Qb denotes the charge of the corresponding part of the system (doped to the substrate or adsorbed
to the system) after the change.

Now I am trying to find out the Hirshfeld charge from population analysis. But I could not download the file named 'MoS2 (0 0 1) 3d (0 0 1).outmol'. WHow can I download this .outmol file. How can I find the value of Q from .outmol file.

Kindly give some suggestions.
