Huge thanks to everyone who took BST272 (Computing Environments for Biology) this year! It’s an intense few weeks as intro to working at the terminal, and we hope folks build on it in courses like BST281. This was our first year integrating AI into the curriculum—thanks for all the great feedback!

6/ We found that Parathaa performed in F1, precision, and recall just as well or better than commonly used amplicon assignment methods while also allowing for finer species resolution.

5/ We validated Parathaa on seven synthetic Silva datasets and historic holdout data from GTDB using both full‑length 16S rRNA amplicons and amplicons of the V1V2 and V4V5 regions.

4/ Parathaa works in two main steps:
- Build an optimized, primer‑specific map linking phylogenetic placement to taxonomy.
- Apply this map to assign zero or more taxonomic labels to each sequence.
- Build an optimized, primer‑specific map linking phylogenetic placement to taxonomy.
- Apply this map to assign zero or more taxonomic labels to each sequence.

3/ Parathaa aims to address these issues by directly modelling taxonomic sequence ambiguity within sequenced amplicon regions: i.e. allowing for assignments to multiple taxonomic labels when phylogenetically warranted.

2/ Amplicon data often contains unique biases due to primer incompatibilities and the inability to differentiate between certain microbes due to low sequence variability, especially at the species level.
