The NG50 of 4 assemblers on datasets from E.coli with different sequence coverage and k-mer values.

<p>(A) 20x, (B) 40x, (C) 80x, and (D) 160x. Illumina error model and 75 bp reads were used. Note that (C) and <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0039232#pone-0039232-g003" target="_blank">Figure 3(B)</a> are the same. The NG50 values are mostly saturated on the sequence coverage of 80x for all the assemblers.
