Porechop is a tool for finding and removing adapters from Oxford Nanopore reads.
Adapters on the ends of reads are trimmed off, and when a read has an adapter in
its middle, it is treated as chimeric and chopped into separate reads. Porechop
performs thorough alignments to effectively find adapters, even at low sequence identity.

Porechop also supports demultiplexing of Nanopore reads that were barcoded with
the Native Barcoding Kit, PCR Barcoding Kit or Rapid Barcoding Kit.
