You cannot add or remove atoms from a group (or, more precisely, it's  
too messy to be worth the effort), but you can replace a residue by  
another one. That is how my mutation code example works. With MMTK 2.5,  
you can also use the new facilities for building groups from scratch,  
but you don't seem to need this as you only work with standard amino
