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.
Figure 2 from my recently pre-printed manuscript on the completeness and accuracy of Nanopore long-read only bacterial genome assembly for Enterobacterales. a) tile plot of chromosome circularisation, with assembler on the x-axis and sample on the y-axis, shows that the consensus long-read only assembler, Autocycler, circularised more chromosomes at 95% (87/92) than any other long-read or hybrid assembler. b) complex upset plot of plasmid reconstruction, showing that the best plasmid reconstruction was achieved by long-read assemblers incorporating the separate plasmid assembly tool, Plassembler, namely Autocycler and Hybracter, reconstructing >96% of plasmids.

Delighted to see our paper studying the evolution of plasmids over the last 100 years, now out! Years of work by Adrian Cazares, also Nick Thomson @sangerinstitute.bsky.social - this version much improved over the preprint. Final version should be open access, apols.

Ever run `install.packages()` and wish it were faster, smarter, and more reliable?

The {pak} package speeds things up with parallel downloads, dependency solving, and reproducible installs.

Come and work with Nicole Stoesser and I in Oxford with the fantastic team @modmedmicro.bsky.social - great opportunity for a postdoc in microbial genomics to do some creative research with great datasets as part of our HPRU.

Great collaboration with @ukhsa.bsky.social #HPRU colleagues #nicolestoesser and the NEKSUS consortium of 9 NHS trusts in England

Overall, using R10.4.1, super-high accuracy basecalling and autocycler, we can reliably infer marker geens (MLST/ARGs etc) and feel that performance was good enough to drop Illumina sequencing for the NEKSUS study (more to follow in due course!)

Dot showed that overall, @rrwick.bsky.social Autocycler appears to outperform other long read assemblers and long read only assemblies are extremely accurate (median Q-score of 67). Long read polishing helps small amount + benefits from short read polishing are very small (only for worst assemblies)

Sometimes you meet absolutely incredible bioinfo-magicians.
It was a huge privilege when @shenwei356.bsky.social
joined our group for a year on an @embl.org sabbatical.
While here, he developed a new way of aligning to
millions of bacteria, called LexicMap 1/n

Plasmids promote antimicrobial resistance through Insertion Sequence-mediated gene inactivation.

Combining experimental and computational approaches, we unveil how two of the most prevalent bacterial MGE accelerate the evolution of AMR. 🧵👇🏻

Great figure, I'm sure this is a dim question but why does it seem to have a cyclical pattern with outliers every ten years or so?

Interesting but then why doesn't famotidine have the same risk? (Or does it!)

Delighted to see this paper from danderson123.bsky.social 's PhD out. We have been building tools for AMR gene detection for over a decade now, but multicopy genes remain challenging. Dan shows that with a gene-space de Bruijn graph and long reads, you can do well
