Figure 7From: Efficient parallel and out of core algorithms for constructing large bi-directed de Bruijn graphsThis figure illustrates the subtle differences between internal graph representation of velvet and the bi-directed graph. (a) de Bruijn graph representation in velvet for the read fragment above, note velvet keeps track of only the first amino-acid symbol from the forward and reverse compliments. (b) bi-directed graph representation for the same read fragment.Back to article page
