How bwa-backtrack trim reads

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. WebTrim reads by quality. Discard reads by quality/ambiguity. Filter reads by k-mer coverage (recommended for the de novo assembly) Normalize k-mer coverage (recommended for the de novo assembly) As shown before, both the presence of low quality reads and adapters are reported in the fastqc output. Adapters are usually expected in small RNA-Seq ...
