All Gromacs programs generate default groups based on the contents of the files
If you're only getting System, Water, and SOL, then the file you've passed to
genrestr contains only water or you are otherwise overriding the default groups
by using another index file (which we can't tell because you haven't provided
your command line). Check the contents of your files.
