Hi,

As far as VMD (and NAMD, I think) are concerned, you can put whatever
you want in the residue field of the PDB file, even letters mixed with
numbers; e.g.,

9998
9999
A000
A001
...

Whatever's easiest for what you're doing. VMD will keep the residues in
the correct order, though atom selections like "resid > 9999" will give
you zero atoms since int(A000) -> 0.

Cheers,
Justin
