# The PDB file format is fixed-field, 80 columns. From the spec:
#
# COLS DATA
# 1 - 6 "HEADER"
# 11 - 50 String(40)
# 51 - 59 Date
# 63 - 66 IDcode
#
# Thus, positions 7-10, 60-62 and 67-80 are spaces. The Date must be in the
# format DD-MMM-YY, e.g., 01-JAN-70, and the IDcode consists of numbers and
# uppercase letters. However, examples have been seen without the date string,
# e.g., the example on the chemime site.
