Figure 4.

An example to illustrate the performance of the PGA. (A) Linear mapping between given target contigs (red bars) and a reference genome (blue bar). The purple lines represent the connections of the interior BLASTN matches and the light blue lines represent the connections of the terminal contig BLASTN matches. The name (number) of each contig is indicated below the red bars. (B, inset) The fitness matrix for these contigs derived from the reference genome. The smaller the matrix value, the shorter the distance between a pair of contigs. Red boxes indicate scores that provide correct information to PGA; the blue boxes indicate scores that provide false information, which may predict an incorrect assembly.
