Plasmid classification and binning with Sergio Arredondo-Alonso and Anita Schürch (#40)

December 30, 2019

Does a given bacterial gene live on a plasmid or the chromosome? What other genes live on the same plasmid?

In this episode, we hear from Sergio Arredondo-Alonso and Anita Schürch, whose projects mlplasmids and gplas answer these types of questions.

Amplicon sequence variants and bias with Benjamin Callahan (#39)

November 29, 2019

In this episode Benjamin Callahan talks about some of the issues faced by microbiologists when conducting amplicon sequencing and metagenomic studies. The two main themes are:

• Why one should probably avoid using OTUs (operational taxonomic units) and use exact sequence variants (also called amplicon sequence variants, or ASVs), and how DADA2 manages to deduce the exact sequences present in the sample.
• Why abundances inferred from community sequencing data are biased, and how we can model and correct this bias.

Issues in legacy genomes with Luke Anderson-Trocmé (#38)

October 22, 2019

In this episode Luke Anderson-Trocmé talks about his findings from the 1000 Genomes Project. Namely, the early sequenced genomes sometimes contain specific mutational signatures that haven’t been replicated from other sources and can be found via their association with lower base quality scores. Listen to Luke telling the story of how he stumbled upon and investigated these fake variants and what their impact is.
