CBCB genomes

  • a bacterial genome. Instead of E. coli, we can use S. aureus USA300, which has sequence data in SRA from 454 and Illumina, paired and unpaired. Daniela has already assemblied it using CA, Newbler, Velvet, SOAPdenovo, and Maq (using its comparative assembly mode, where it aligns to a reference).
  • A medium-sized eukaryote. I'd like to use the Argentine ant or the Bombus impatiens bee - I've just written to Gene Robinson to ask about the bee.
  • Another eukaryote, ideally a larger one. Human would be great, but we just don't have enough time to do multiple human assemblies. So maybe another insect, or perhaps a plant if we can find one for which data is available.

If we can agree on the data sets, then the next step would be to design the experiment - decide in advance which assemblers to run and how many ways to try each one. I'm thinking we should also trim all the data with Quake.

    • "according" to kmerFreq , should probably not use -K >47
    • longer kmer => longer scaffolds (K=63 : largest N50scf)
    • longer kmer => shorted contigs (K=31 : largest N50ctg)
    • K40+ too large: no "valley" in the kmerFreq histogram

  • Comments
    • Human chromosome 14. The chromosome may change, but this is a new data set with 100X coverage in 100bp and 76bp reads, just assembled by the Broad group using Allpaths-LG and Soap. We've downloaded the data and Todd is going to create a data set representing just chr 14, to make it feasible. We'll then try to assemble that data w/all 3 assemblers: CA, SOAP, Allpaths-LG.
  • Illumina chr14 reads (aligned with bowtie & corrected)
 /fs/szattic-asmg8/treangen/*fastq
 hard to align: bowtie -5 20 -3 20 -e 1000 ...
 jumping reads: only the ones aligned within coorect mean, stdev selected; these libraries usually have a high % of short inserts!!!
