This two-day hands-on workshop will introduce biologists to microbial genomics and transcriptomics. The primary focus will be on genome assembly and annotation, and subsequent transcriptome analysis, of bacteria.
We will be analyzing a stock data set, and we will be using the Amazon cloud.
- Logging into the Amazon Cloud
- Short read quality and trimming
- Genome assembly (with SPAdes or MEGAHIT)
- Genome annotation (with Prokka)
- RNAseq analysis
- Differential expression analysis
Attendees will need to bring a computer with a Web browser, an Internet connection, and an ssh client; Windows users should install MobaXterm before the workshop.

For many years I have been wondering about the best way to get more formal credit for blog posts I have written. It seems like the simplest way to do this would be to get a DOI for a blog post under some sort of publishing system and to use that DOI as the citable unit for the post. I remember a while back Titus Brown wrote about this exact idea: Posting blog entries to figshare – Living in an Ivory Basement but I have not seen much else out there on ways to do this and what the implications are. Anyone else out there know examples of how people have gotten DOIs for blog posts and if this has been useful? Thanks
Interesting new #OpenAccess PNAS paper from C. Titus Brown: Scaling metagenome sequence assembly with probabilistic de Bruijn graphs. Of course, if you follow Titus on Twitter or his blog you would know about this already because not only has he posted about it but he posted a preprint of the paper on arXiv in December.
Check out the press release from Michigan State. Some good lines there like “Analyzing DNA data using traditional computing methods is like trying to eat a large pizza in a single bite.”
A key point in the paper: “The graph representation is based on a probabilistic data structure, a Bloom filter, that allows us to efficiently store assembly graphs in as little as 4 bits per k-mer, albeit inexactly. We show that this data structure accurately represents DNA assembly graphs in low memory.” This is important because right now most assemblers for genome data use a ton of memory.
Anyway the software behind the paper is available on GitHub here. Assemble away.
