Many laboratories have ramped up nanopore sequencing for SARS-CoV-2 surveillance, but are in dire need of bioinformatics support. Here we present poreCov, a high-throughput software pipeline for reliable genotyping and reference-based genome reconstruction of SARS-CoV-2 samples based on nanopore tiled amplicon sequencing focused around the ARTIC protocol. On GitHub! Big kudos @CaSe Group Jena!

Finally! Together with great colleagues from ANSES in France (among others) we describe a new genus Chlamydiifrater gen. nov. inside the family Chlamydiaceae isolated from flamingo! The bioinformatics part actually started with Fabien visiting us in 2016 and 2017 to learn about assembly and finally found its successful conclusion with the analysis of nanopore data and high-quality genomes.

Questions about the characteristics, spread and significance of mutated variants of SARS-CoV-2 play a major role in the progress of the pandemic. Here, we summarize in the “Deutsches Ärzteblatt International” (in German) how molecular surveillance using whole genome sequencing is carried out at the Robert Koch Institute.

RNA-Seq workflows are a dime a dozen. Nevertheless, we are happy to present RNAflow as an easy to use pipeline for gene expression calculation with less configuration effort. Made possible by Nextflow and most importantly Marie ;) !

14. November 2020
Genomic surveillance is limited not only by the speed at which genomes can be shared, but also by the speed at which they reach the right person or algorithm to analyze them. DarkQ is a proof-of-concept on how we might share data for genomic surveillance in the future.

10. November 2020
Very happy that this is finally out, a review on workflows and tools that have been developed by the virus bioinformatics community as a rapid reaction to the COVID-19 pandemic! Including a comprehensive (yet incomplete) collection of tools and resources for virus detection, annotation, tracking and drug design.

29. October 2020
Freshly out! Our genome comparison of 33 Chlamydia strains! All started with Lisa’s master thesis, we run into issues defining proper core gene sets (roary n = 7, really?!) and developed RIBAP together with Kevin! All would not have been possible without the supervision of the great post-prof Konrad! Thx to all involved!

20. October 2020
Martin’s first paper as a single author (invited perspective in Molecular Ecology Resources)! Based on a recent publication by Freedman et al. on errors in de novo transcriptome assemblies, Martin shares some thoughts on the current status and future of this area.
