To summarise our recent pre-print: Autocycler, the automated consensus assembler, when used with Nanopore long-read only Enterobacterales assemblies, produces more complete chromosomes and plasmids, with an accuracy comparable to hybrid assemblies.

For anyone who has used pling for comparing plasmids using rearrangement distances ("how many structural events apart are these plasmids"), here's how to tweak parameters, and integrate it with typing info, and the host phylogeny

Clustering of plasmid genomes for genomic epidemiology by using rearrangement distances, with pling
Integration of plasmids into genomic epidemiology is challenging, because there are no clearly defined evolving-units (equivalent to species), and because plasmids appear to evolve as much by structur...

Happy to see this out - please try my code and break it! Also come see me at #ABPHM25 in the showcase today, where I’m presenting AMRGen, an R package for combining and exploring AMR geno pheno data. It was used to help make many of these rules interpretamr.github.io/AMRgen/
Excited to share the first beta release of AMRrules at #ABPHM! (Poster 42 tonight)
