Figure 1

The distribution of read lengths in 454, Illumina and PacBio budgerigar sequences. The reads are binned into 5 bp buckets based on their lengths, and the fraction of reads (normalized by the size of the largest bucket) falling into each bucket is shown. Thus, curves shifted towards the right indicate longer read lengths. The reads labeled “20 Kbp”, “8 Kbp” and “3 Kbp”, “FLX Titanium” and “FLX Titanium XL+” are 454 reads. The reads labeled “PacBio pre-release C2” are uncorrected PacBio reads. The Illumina read lengths appear as colored square boxes, since these read lengths are uniform. The “Illumina Duke” reads are of length 76, The “Illumina UK” reads are of length 101, and the “Illlumina BGI” reads are of lengths 90 or 150. The longest reads come from PacBio sequencing, followed by 454 FLX + (i.e., FLX Titanium XL+) sequencing.
