Team 2 Report : SOAPdenovo 2
Outline
- SOAP stands for Short Oligonucleotide Analysis Package
- It uses a sparse de Bruijn graph to assemble the genome
- It is developed by the Beijing Genomics Institute
- One of the unique features of this assembler is that it uses multiple k-mer sizes in order to extract extra information from repeats.
Using Soapdenovo
- The user supplies a configuration file which contains information on the location and type of data as well parameters which affect the speed and quality of the assembly.
- When using Soapdenovo it is important to consider memory requirements as well as the quality of the reads.
Read assessment
- Two adapter trimmers were tested, Skewer and AdapterRemoval.
- Skewer was faster and easier to use.
- Error correction was done with Musket. However, fewer reads were corrected than anticipated.
- Kmer analysis done with kmergenie indicated that the optimal kmer size for the de Bruijn graph is 61 bases.
