Brief overview of goals and data input characteristics

Kevin laid out some of the logistics of the class.

A broad goal: For each chromosome in the slug, we want the full sequence in DNA bases. Since it is unlikely to be completed in the timeframe of one quarter, some smaller goals: build contigs and have an idea of the scaffold to arrange the contigs in.

Inputs: Sequencing data from various machines. Some of the characteristics of these machines/techniques:

Sanger capillary

  • ~800bp reads[1].
  • Q (quality value) ~30
  • ~$1/read, expensive because primers must be attached to each read.


  • ~400bp reads[2].
  • Q ~20
  • Pyrosequencing
  • $5000/run/~1m reads, no downscaling.
