Progressive improvement of gene prediction metrics in 124 human gut metagenomes.

<p>Gene prediction metrics are improved when using an automated kmer size in SOAPdenovo and with assembly revision (correction of base errors, short indels, and chimeric contigs), compared to a fixed kmer size of = 23 in SOAPdenovo and no assembly revision. The Kmer size is estimated as the closest odd number greater than half the average read length for a sample. Numbers reported are in percent improvement of the respective quality metric. The calculated Kmer for each sample is given in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0047656#pone.0047656.s008" target="_blank">Table S8</a>.
