a. Distribution of the read lengths for the GS FLX shotgun sequencing (average 248.5 bp). b. Distribution of read lengths of the GS FLX Long Paired End sequencing. The yellow curve represents the raw reads (average read length 210 bp). These were separated into those containing the linker sequence and those without. The reads containing the linker sequence were separated into two paired end reads, one to the left of the linker (green curve; average read length 93 bp) and those to the right of the linker (red curve; average read length 96 bp). Reads without the linker sequence (blue curve, average read length 191 bp) were added to the assembly as additional shotgun reads.
