Do you make core genome alignments for phylogenomics? @monaltaouk and I explored how including sites with some missing data (a soft core) can improve analysis, especially for large datasets. microbiologyresearch.org/con… (1/4)

And the benefits grow with dataset size! A 100% strict core may work fine for small datasets (e.g. ~10 genomes) but is devastating for very large ones (e.g. 1000 genomes). A 95% soft core works well across all dataset sizes. (3/4)

To make producing soft core alignments easier, we developed Core-SNP-filter, a simple and efficient tool to process SNP alignments with user-defined thresholds. github.com/rrwick/Core-SNP-f… (4/4)

New year, new assemblies! I'm excited to announce Autocycler, my new tool for consensus assembly of long-read bacterial genomes! It's the successor to Trycycler, designed to be faster and less reliant on user intervention. Check it out: github.com/rrwick/Autocycler… (1/5)

However, Autocycler still allows users to manually intervene when they would like to. So it aims for the best of both worlds: either hands-off automated assemblies or hands-on curated assemblies, as the user sees fit. (4/5)

Autocycler is still new and evolving. I'll continue to improve it based on your feedback. A big thank you to the alpha testers who gave me feedback before this release! Give it a try and share your thoughts. (5/5)

Just had my first experience with CycloneSEQ data and shared my findings in this blog post: rrwick.github.io/2024/12/17/… How does CycloneSEQ compare to @nanopore? I looked at both read-level and consensus-level accuracy. Check it out!

If you want to try out the new --bacteria Medaka polishing option after reading Ryan's thoughts in his latest blogpost, the newest Hybacter v0.10.0 release now includes it as the default github.com/gbouras13/hybract…

A little bit overdue, but here are my thoughts on @nanopore's recent release of Medaka: rrwick.github.io/2024/10/17/…

Our OnION sequencing computer now has a little sibling: Spring OnION! Short post with some stats and benchmarks: rrwick.github.io/2024/08/16/…

I finally got around to testing HERRO (github.com/lbcb-sci/herro), the new @nanopore read correction algorithm which takes simplex ONT reads to PacBio-HiFi-level accuracy. I was impressed! Findings are on my blog in a two-part post: rrwick.github.io/2024/07/26/… rrwick.github.io/2024/07/31/…

How low can you go? Short-read polishing of Oxford Nanopore bacterial genome assemblies. Published #OpenAccess and fee-free in #MGen using a #PublishAndRead agreement: doi.org/10.1099/mgen.0.00125…

It has been public for a while, but with #VoM2024 starting, today is as good as any to introduce our new tool phage genome annotation tool Phold. Phold uses structural homology to assign functions to phage proteins (1/n)

I am excited to win a CZI EOSS grant! This is the first grant I have ever won after 20 years in science. It feels wonderful to finally be funded for my open-source contributions. With @wytamma we will deliver the next generation of my popular Snippy software! 🦘🦘🦘

New blog post: rrwick.github.io/2024/06/11/… ONT-only bacterial assemblies are much better than they were only a couple of years ago. Often <10 errors in the whole genome. Does that mean that less short-read sequencing is required for polishing? See my post for the answer! (1/4)

The paper also introduces George's tool Pypolca: github.com/gbouras13/pypolca This is a reimplementation of the POLCA polisher (by @AlekseyZimin5) that is easier to install and run. Pypolca also has some new options (e.g. --careful) which give it more flexibility than POLCA. (3/4)

I'm a big fan of Pypolca and use it a lot. If you had to pick one and only one tool for short-read polishing of ONT bacterial genome assemblies, it should be Pypolca! (4/4)
