So, you should first set "iuserfunc" in settings.ini to the corresponding index, after that, you can use Multiwfn to perform various analysis on it, such as plotting it as curve/plane/isosurface map (main functions 3,4,5), integrating in atomic spaces (usually main function 15), etc. When Multiwfn asks you to select the function to be studied, choose "User-defined function".

I am trying to perform an electron momentum density (EDM) analysis from gaussian16 .fchk and .wfn files. Which main function and sub functions do I need to follow to do so?
