Renumbering

[Francesco Pietra]

Hi;

I would like to renumber, starting from 1, column 6 (i.e, 428 become
1, 429 becomes 2, etc for a very long list)

ATOM   3424  N   LEU B 428     143.814  87.271  77.726  1.00115.20       2SG3426

Distinctive character is column 5, i.e., it must be set that only
lines containing "B" should be renumbered.

As you can see, the number of lines for a particular value in column 6
changes from situation to situation, and may even be different for the
same name in column 4. For example, LEU can have a different number of
lines depending on the position of this amino acid (leucine).

I was unable to set non-proportional characters, sorry.

Thanks for help
