Hi,

I am trying to align some tumor miRNA sequencing data to a viral genome using Bowtie2. In order to achieve the results I need, I need for Bowtie2 to only align a certain number of nt to my reference genome. Is there any way to tell Bowtie2 to only align the first 17 nts to my genome and ignore the last 5?

Thank you!

Find this option on the Bowtie2 tools form at:

  • Select analysis mode > 2. Full parameter list

  • Do you want to tweak input options? > Yes

  • Trim that many bases from 3' (right) end of each read before alignment (notes) -3/--trim3; default=0
