Figure 4

Frequency of contigs of various sizes from the all catfish reference assembly. The X-axis represents contig size (number of reads per contig). The curved line denotes the cumulative percentage of reads assembled. Note that a small number of very large contigs account for the majority of total reads. For instance, less than 0.3% of the contigs with over 100,000 reads per contig represent over 32% of all sequence reads assembled.
