Genome Project
Brugia malayi has a diploid genome of approximately 110 Mb, organized in 6 pairs of chromosomes (five pairs of autosomes and one pair of sex chromosomes). In addition to the nuclear genome, B. malayi has a mitochondrial genome of about 14kb, and the genome of the harbored bacterial endosymbiont Wolbachia sp (1-2Mb).
The B. malayi genome project has been completed by The Institute for Genomic Research. Whole Genome Shotgun sequencing was used to obtain more than eight-fold coverage of the genome. The complete genome was assembled into approximately 8200 scaffolds and deposited in GenBank. The accession for the WGS project is AAQA00000000 and consists of sequences AAQA01000001-AAQA01029808.

Data
Original Traces
Libraries:
* 2K : bulk of the sequence @TIGR
* 15-20 K @TIGR
* 8,000 BAC clones @Children's Hospital Oakland Research Institute. (!!! no NCBI TA submission)
* 454 Titanium paired-end (NEW)
** 500Mbp per run in reads of ~350bp each.
** reads: 80bp to 500bp
** 30% - 50% of the reads contain two mate tags per read
** Each mate tag is ~150bp and the tags are separated by the 42bp "recombi" XLR linker sequence
** lib mean,std =~ 28K,6K
** duplication problem: 2-4 identical copies of each pair???

Problems:
- All library insert sizes are underestimated
- The contaminant reads align at ~91-93% id to the contaminant ctgs while the Mt/We reads align at 99% id to Mt/We finished seq. What %id thold to use for contaminant?
