How bwa-backtrack trim reads
WebMapping of reads to assembly. In order to correct a given assembly, nanopolish needs a mapping of the original reads to this assembly. We are using the software package BWA to do this. BWA is a software package for mapping low-divergent sequences against a large reference genome. It consists of three algorithms: BWA-backtrack, BWA-SW and BWA … WebWe will use this option since we did not trim our reads. NOTE: Our reads are only 36 bp, so technically we should explore alignment with bwa or Bowtie1 to see if it is better. However, since it is rare that you will have sequencing reads with less than 50 bp, we will show you how to perform alignment using Bowtie2.
