The purpose of this project is to analyse a dataset of 16S amplicon sequencing to assess fish biodiversity. Our goal is to run one or more bioinformatics pipelines, perform simple ecological analyses, and compare results. A driving question to this project is: does using different bioinformatics protocols make a difference in the biological conclusions?

Steps:
- Demultiplex Illumina sequencing data (using
obitools/ngsfilter
). - Basic preprocessing and length filtering with fastp.
- Create a custom reference database using only fish species from the OBITools reference database (see the Wolves tutorial for more information).
- Run different bioinformatics pipelines.
- Perform simple ecological analyses.
- Compare results of pipelines.
