Eco-Flow/nanoporemetabarcoding

Eco-Flow/nanoporemetabarcoding is a Nextflow pipeline -written using the nf-core standards- for processing -quality control, demultiplexing, and clustering- and annotate nanopore metabarcoding data. Annotation is performed at different taxonomic levels on the consensus sequences, using the BLASTnt database and taxonomizr.

Overview

Overall, the pipeline performs the following steps:

• Performs read filtering, trimming, and quality control on both raw and processed sequencing reads.
• Demultiplexes reads based on tag–primer combinations
• Groups amplicon reads into ‘species’ consensus sequences
• Annotates consensus sequences based on the best matching reference hit against BLAST database
• Assigns taxonomy to annotated sequences using NCBI taxonomy identifiers
