If you could get the Bader's program to work let me know please. It is been a while that I can't compile the code on linux. People say that you need intel fortran compiler (expensive) and none of native linux compilers (gfrotran,g77,g95 and gcc) work with the code.
Multiwfn is really great for this purpose. Other than that, you can do a number of visualization and intepretation just by using files of gaussian or nwchem.
