Genome Assembly

Hybrid Metagenomic Assembler OPERA-MS

Readers working on metagenome assembly will enjoy a new paper by Denis Bertrand et al that came out in Nature Biotech. I have not gone through the algorithm yet, but would like to do, when the authors make a pdf copy available.

Genome Assembly is a Nearly Solved Problem with Long Reads

I Wish Ryan Wick Does not "Publish" his Long Read Assembler Comparison

We encourage our readers to take a look at the comparison of long read assemblers by Ryan Wick and Kathryn Holt. The authors benchmarked five different assemblers, namely Canu, Flye, Ra, Unicycler and Wtdbg2.

Using Synteny in Genome Assembly, an Interesting New Direction?

In this week’s commentary in the membership section, we reviewed the recent advances in the genome assembly field. One paper mentioned there is an excellent PLOS Compbio. review on scaffolding by Jay Ghurye and Mihai Pop. I will skip over the discussion on various long-read technologies and mention a topic with the potential to make substantial improvement in genome assembly.

Pay Attention to These Three New and Impressive Genome Assemblers

The genome assembly field continues to be highly active, and the researchers are still coming up with algorithms making significant speed improvements. The following three projects are definitely worth your attention.

Contamination Nightmare in Microbial Genome Assemblies

While working on RNAse P in microbial genomes, I noticed something very puzzling. An archaeal protein that was never seen before in bacteria was present (and even annotated) in a newly sequenced bacterial genomes. If true, it could completely change the evolutionary understanding of the RNase P protein families.

Practical Dynamic de Bruijn Graphs

The de Bruijn graphs are immensely helpful in assembling Illumina sequences, but they often occupy massive amounts of memory, especially for large raw datasets. Our readers interested in representing de Bruijn graphs in compact space should not miss a recent paper by Victoria Crawford, Alan Kuhnle, Christina Boucher, Rayan Chikhi and Travis Gagie. The paper is published in Bioinformatics, but the journal link is not open-source.

Genome assembly algorithms through jigsaw puzzles - III

This is the third installment of “genome assembly algorithms through jigsaw puzzles”. We usually post them here every Tuesday, although we are late this week. You can find all those pieces in one place (and some more) at this link. We are developing this tutorial to explain genome assembly algorithms in a simple manner. In fact, rather than explaining, we expect you to discover the answer by manually solving a jigsaw puzzle. Later we show you how your solutions are related to the commonly used algorithms and their variations.
