Figure 1. Comparison of de novo assembly with a distinct k-value.

Three assembly programs, ABySS, Velvet and OASES, were tested with a distinct k-mer from 31 to 95. In each assembly program, the number of contigs, the N50 length, and the average and maximum contig length were calculated using the assembled contigs longer than 100 bp (black), 200 bp (orange), 300 bp (blue), 400 bp (green) and 500 bp (pink).
