yeah ok, it was created via another program, (aten), as antechamber produced
the following msg when trying to create from a pdb file which i have also
antechamber -i tmm_rs_rs_rr.pdb -fi pdb -o tmm_rs_rs_rr.mol2 -fo mol2

The atom number exceeds the MAXATOM, reallocate memory
Info: the bond number exceeds MAXBOND, reallocate memory automatically

Info: the atom number exceeds the MAXATOM, reallocate memory automatically
For atom[37]:O, the best APS is not zero, bonds involved by this atom are

The frozen atom type can only be 1, 2, 3, 7 (aromatic single), 8 (aromatic
double)Error: cannot run "/home/user/Desktop/andy_amber/amber10/bin/bondtype
judgebondtype() of antechamber.c properly, exit

is this perhaps the root problem? i was hoping it might have been a case of
simply editing either the pdb or mol2 file, apologies for the confusion.
