[PyMOL] Restoring of atom number order

Dear Pymol Users!


I've forced with the problem of missing correct atom numbering order during
processing of my pbd structure.


E.g I had a mollecule of caffein where each atoms had its own number ( e.g
N1 or N3 etc)

HETATM 2252  N1  CFF A 330       9.174 -33.156 -31.881

HETATM 2257  O11 CFF A 330      10.781 -34.432 -33.079
1.00142.40           O
HETATM 2258  C12 CFF A 330       8.923 -35.204 -35.004

HETATM 2259  C4  CFF A 330       7.287 -33.864 -33.735
1.00146.85           C
HETATM 2260  C5  CFF A 330       6.925 -33.068 -32.699
1.00145.81           C

HETATM 2262  O13 CFF A 330       7.552 -31.908 -30.705
1.00147.52           O
HETATM 2263  N7  CFF A 330       5.617 -32.775 -32.828
1.00147.22           N
HETATM 2264  C8  CFF A 330       5.235 -33.422 -33.954
1.00148.06           C
HETATM 2265  C14 CFF A 330       4.727 -31.975 -31.994
1.00145.92           C

as the consequence I've obtained pdb of this molecule with changing atom
order and (that is expesiaaly crusial ) missing atom names

in the second example you can see that all Nitrogens are just N without
numbers etc.

1- Does it possible to resutn to the second pdb file initial correct atom
numbering ?
2- How I could prevent in future deleating of such numbers ? (It's occured
after I add missing Hydrogens and connect enties to my mollecule by PYMOL)


Thanks for help,

James
