It depends on what the program does, right?  If the program doesn't like the
atom type you give it, it has two options. 1) give it the scattering factor of
an atom type that corresponds to the first letter in the atom name or 2) totally
ignore that atom.  In the latter case your scattering factor for that atom WILL 
be off.  However, like my previous post mentioned, this should not significantly
affect the structure factor calculation on a molecule containing 1000+ atoms.
