Fig. 4From: Impact of library preparation protocols and template quantity on the metagenomic reconstruction of a mock microbial community a Mock community relative abundances across each library prep kit and across each dilution including the TruSeq 200Â ng Control library (top). b Principal coordinates analyses of Euclidean distances derived from mapping reads to the mock community reference genomes (left column) and of k-mer frequencies (right column, averaged sample k-mer frequencies from k2-k10 sample by sample k-mer distance matrices). Individual samples are colored by either library preparation (top) or starting input quantity (bottom). The unamplified 200Â ng control library is represented by the red point in each ordinationBack to article page
