STEMLOOP
Vertical bars ('|') indicating
the base pairs. The
associated loop is shown to
the right of the stem. If either
the stem or loop is too long
to be displayed in its entirety
on the line, then only that
part that fits on the line is
shown. The first and last
coordinates of the stem are
displayed on the left, and
the length of the stem (size),
the number of bonds in the
stem (quality), and the loop
size are shown on the right.
