Taxonomic assignments of sequences. Assignment of each class of sequences to the least common ancestor of their BlastX hits (e-value = 1e^-5) using MEGAN. A) Distribution of assignments on the NCBI taxonomy tree. The pie graphs are proportional to the number of sequences assigned to that node, whereas the numbers are the accumulative sum of sequences assigned within that subclade. B) Expansion of the Tetropoda node. The yellow arrow indicates the placement of the garter snake on the taxonomic tree.
