PHE researchers Mark Stoeckle and Cameron Coffran developed a new software, TreeParser, that helps generate Klee diagram “heat maps” of genetic biodiversity (freely available on the PHE website https://phe.rockefeller.edu/barcode/klee.php ). Their work appears today in Nature Publishing Group’s open access journal Scientific Reports https://www.nature.com/srep/2013/130911/srep02635/full/srep02635.html The resulting Klee diagrams are both beautiful and scientifically informative. In the figure below, bird and butterfly species appear as discrete “hot blocks” of sequence along the diagonal.
