**Dataset formats**

The input dataset is in tabular_ format and must contain a scaffold or 
chromosome column and a position column.  The output dataset is in text_ 
format as described below.
(`Dataset missing?`_)

.. _tabular: ./static/formatHelp.html#tab
.. _text: ./static/formatHelp.html#text
.. _Dataset missing?: ./static/formatHelp.html

**What it does**

This tool extracts primers for SNPs in the dataset using the Primer3 program
(Steve Rozen and Helen J. Skaletsky, 2000).
The first line of output for a given SNP reports the name of the assembled
contig, the SNP's position in the contig, the two variant nucleotides, and
Primer3's "pair penalty".  The next line, if not blank, names restriction
enzymes (from the user-adjustable list) that differentially cut at that
site, but do not cut at any other position between and including the
primer positions.  The next lines show the SNP's flanking regions, with
the SNP position indicated by "n", including the primer positions and an
additional 3 nucleotides.
<!-- is this precomputed?? how, where is the user-adjustable list? -->
