Then either change your box size to make it slightly larger (and since you're using -maxsol, it won't change the number of molecules), or change the value of -seed when running genbox to get a different configuration until you've got one that you're satisfied with.

        I have to create a box with given number of water molecules
        (spc/e) in it.  So I use genbox -cs spc216.gro -maxsol n -box ,
        with appropriate box size and n.
        But I observe in the out.gro that some atoms are outside the
        box, so How do I make genbox to keep all atoms within the box
        specified?


    If you plan on using periodic boundary conditions, "outside" is
    irrelevant...
