The problem with CNT is, where one starts to set the charges = 0 and
where where one stops and this approach is quite limited (I think) for
functionalized CNT; thus I would use RED Server Dev/PyRED: it has a
robust algo. to determine chemical equivalencing (which is a headache
in CNT anf functionalized CNT) and as always use the building blocks
appraoch to limit the size of your molecular system and control the
conformations of these elementary building blocks...
