With RASMOL you saw the "molecule": read this as "a chunck of nanotube
that is larger than the unitcell". And there is nothing wrong with your
molecule.

Note that in your input A=4.32, but the x coordinates in your input span
the range between 0 -- 7.2 angstroms (why: see above). Therefore either
"cut the atoms with large x values" or enlarge the A parameter thus
making the supercell.
