SNPsvg

I wrote a quick Perl script to visualize SNPs in a gene from experimental evolution sequencing data.  Useful for making figures when one gene is hit by mutations in multiple lineages.  It outputs an SVG file with the reference sequence and the changes.

For the moment, it only visualizes substitutions, not insertions/deletions or anything more exotic.  More to come.

Example: SNPs found in Pseudomonas aeruginosa gene PA2449 (converted to PNG)

Turdus merula

Turdus merula

The Common Blackbird (Turdus merula) is a species of true thrush. It is also called Eurasian Blackbird (especially in North America, to distinguish it from the unrelated New World blackbirds),[2] or simply Blackbird, where this does not lead to confusion with a similar-looking local species. It breeds in Europe, Asia, and North Africa, and has been introduced to Australia (where it is considered a pest) and New Zealand. It has a number of subspecies across its large range; a few of the Asian subspecies are sometimes considered to be full species. Depending on latitude, the Common Blackbird may be resident, partially migratory or fully migratory.
