A Tinoco Plot (Tinoco et al., 1971) is simple a tool
to investigate possible secondary structure elements in RNA or DNA
single strands. With a given RNA or DNA sequence this tool will
calculate all possible helices and displays them in a two-dimensional
plot. Choosing 'DNA' only Watson-Crick base pairing is
allowed whereas 'RNA' performs also G:U base pairing. The
parameter 'minimum helix length' is used to suppress the
display of smaller helices.
The output formats are PDF, PostScript, CSV, and GIF.
PDF can be displayed by Adobe's Acrobat Reader,
PostScript has also to be displayed by an external viewer
(Ghostscript), CSV is viewable in a spreadsheet program,
and GIF is automatically embedded in a
HTML document as 'inline image'. GIF output is currently
limited to sequences shorter than 200 Nts in length.
