Overlap Graphs

To prepare libraries for this pipeline:

  1. poretools fasta --type 2D <path/to/base/called/reads/> > <name.fasta>
  2. bwa mem -x on2d <indexed_reference.fasta> <name.fasta> | samtools view -bS - | samtools sort -o <name.sorted.bam> -
  3. samtools depth <name.sorted.bam> > <name.coverage>
  • head <name.coverage> # This finds the name of the 'chromosome'; there may be >1.
  1. awk '$1 == "<chromosomename>" {print $0}' <name.coverage> > chr1.coverage
  2. Repeat for paired library
  3. Fill in and into pool1 and pool2 in depth_coverage.R
  4. Stats acquired using poretools stats <path/to/base/called/reads

Reported p20 and p40 values represent percentage of the Zika genome which has at coverage of at least 20/40 reads, respectively.
