On the optimistic performance evaluation of newly introduced bioinformatic methods | SpringerLink (link.springer.com)

So you read about a new, cool method that "improves" on previous methods. But are they really an improvement?

Most research articles presenting new data analysis methods claim that “the new method performs better than existing methods,” but the veracity of such statements is questionable. Our manuscript discusses and illustrates consequences of the optimistic bias occurring during the evaluation of novel data analysis methods, that is, all biases resulting from, for example, selection of datasets or competing methods, better ability to fix bugs in a preferred method, and selective reporting of method variants.

CLIMB-BIG-DATA | Cloud Infrastructure for Microbial Bioinformatics (www.climb.ac.uk)

Antimicrobial resistance is a critical universal issue and scientists need reliable, fast, reproducible tools for their research. The aim of this hackathon is to improve upon/build/extend bioinformatics tools and methods for the AMR community. This year’s hackathon has a special focus on antimicrobial resistance in bacteria.

An FM-index of 400k SARS-CoV-2 genomes (lh3.github.io)

Leonardo Martins tweeted that xz can compress a 1.4 million SARS-CoV-2 genomes in a 39GB FASTA down to 74MB. That is a very impressive compression ratio! This reminds me of my earlier work on FM-index construction.

For an experiment, I downloaded ~400k SARS-CoV-2 genomes from EBI’s COVID-19 data portal (GISAID has ~1.5M genomes but imposes restrictions) and generated an FM-index of these sequences in both strands with ropebwt2

GitHub - marbl/merqury: k-mer based assembly evaluation (github.com)

Here we present Merqury, a novel tool for reference-free assembly evaluation based on efficient k-mer set operations. By comparing k-mers in a de novo assembly to those found in unassembled high-accuracy reads, Merqury estimates base-level accuracy and completeness.
