PDB Plugin, Version 0.1
This plugin reads and writes molecular coordinate data stored in the
PDB file format.
Feature-specific notes:
Since PDB files can only store 99,999 atoms without overrunning the
columns designated for atom indices etc, the PDB plugin doesn't directly
use the atom indices specified in the PDB file as its own indices, instead
it keeps its own independent atom index counter, allowing it to read files
containing millions of atoms. The atom index field for atoms beyond 99,999
may contain alphanumeric characters, or some other unique string scheme,
as has commonly been used in software such as X-PLOR/CNS, and other packages.
Unused data
Various PDB record types and fields are ignored by VMD, in general
VMD doesn't do anything with the sequence data or crystallography-specific
fields in the format, though it does read in unit cell information for use
with periodic image display when possible.
