Figure 2.

The contig length comparison between contigs with and without protein hits. The X-axis represents the contig length, and Y-axis represents the percentage of contigs. Note the high percentage of contigs that do not have significant protein hits in public protein database are in short length (83% less than 600 bp), and the high proportion of contigs with protein hits are long contigs.
