Supplementary Figure 4: Iterative assembly.
From: TruSPAdes: barcode assembly of TruSeq synthetic long reads

A fragment of a genome along with four reads (1st panel) and de Bruijn graphs of these reads constructed for k = 3 (2nd panel), k = 4 (3rd panel), and k = 5 (4th panel). The parameter k = 4 represents the “sweet spot” in the iterative assembly since the de Bruijn graph for k = 3 is over-tangled while the de Bruijn graph for k = 5 is over-fragmented.
