Genome Assembly Pipeline

Our Goals

1. To perform quality control on reads before and after assembling the genome. 2. To evaluate the performance of assembly tools:

  * Abyss
  * ALLPATHS-LG
  * SPADES
  * SKESA
  * Velvet

3. To use the best 2 to perform de novo assembly based on the 50 isolates.

4. To send off the highest quality result to gene prediction.
