Video Tip of the Week: Microbiome Resources From JGI


Just over a month ago an issue of Nature had two articles from the Human Microbiome Project Consortium – you may have seen them, or noticed the Friday SNPets items we had on them. I promised myself that I’d read the articles (which I did), and that I’d visit my old friends the IMG (Integrated Microbial Genomes) & IMG/M (IMG with Microbiome Samples) to see what is new at these powerful microbial genome resources. In today’s tip I decided to take you along on my visit with me, because I found that IMG now has a resource dedicated to the analysis of genomes related to the Human Microbiome Project called the Integrated Microbial Genomes-Human Microbiome Project, or IMG/HMP. We visit both IMG/M (briefly) and the IMG/HMP in today’s tip.

When I referred to IMG as an old friend, I really do feel that way – our tutorial on IMG* was one of my first projects for OpenHelix. I was new, and IMG was new, having been released in March of 2005, only a few months before I created our tutorial (on their June 2005 release, if I am remembering correctly). They have grown into such an extensive, powerful resource. To give you an idea of how fast they have grown & developed, our current IMG tutorial is version 12 and I’ll be working on version 13 as soon as I finish updating our SGD tutorial. When we first created our IMG/M tutorial*, metagenomes were a relatively new concept and the resource included a total of 24 microbiome samples – now it has over 1000!

But enough with the nostalgia, let’s get to the resources! :) IMG/M integrates metagenome data with isolate microbial genome sequences from the integrated microbial genome (IMG) system to enable the analysis of phylogenetic composition and functional or metabolic potential of the aggregate genomes (metagenomes) in microbial communities (microbiomes). Genomes generated as part of the Human Microbiome Project (HMP) are included into IMG/M from RefSeq via IMG. IMG/M resources allow users analyze metagenomes, genomes, genes and functions by making lists of items and then manipulating them in “analysis carts”. Metagenomes can also be analyzed using the tools provided from their ‘Metagenome Details’ page. These options are explained in much more detail than I can cover here in the IMG/M reference that I site below. I also link to the most recent IMG publication, since an understanding of it is essential to understand any IMG/M-based resource.

Announcement of Updated Tutorial Materials: UniProt, Overview of Genome Browsers, and World Tour of Resources

As many of you know, OpenHelix specializes in helping people access and utilize the gold mine of public bioscience data in order to further research.  One of the ways that we do this is by creating materials to train people – researchers, clinicians, librarians, and anyone interested in science - on where to find data they are interested in, and how to access data at particular public databases and data repositories. We’ve got over 100 such tutorials on everything from PubMed to the Functional Glycomics Gateway (more on that later).

In addition creating these tutorials, we also spend a lot of time to keep them accurate and up-to-date. This can be a challenge, especially when lots of databases or resources all have major releases around the same time. Our team continually assesses and updates our materials and in this post I am happy to announce recently released updates to three of our tutorials: UniProt, World Tour, and Overview of Genome Browsers.

Our Introductory UniProt tutorial shows users how to: perform text searches at UniProt for relevant protein information, search with sequences as a starting point, understand the different types of UniProt records, and create multi-sequence alignments from protein records using Clustal.

Our Overview of Genome Browsers introduces users to introduce Ensembl, Map Viewer, UCSC Genome Browser, the Integrated Microbial Genomes (IMG) browser, and to the GBrowse software system. We also touch on WebGBrowse, JBrowse, the Integrative Genomics Viewer (IGV), the ARGO Genome Browser, the Integrated Genome Browser (IGB)GAGGLE, and the Circular Genome Viewer, or CGView.

Our World Tour of Genomics Resources is free and accessible without registration. It includes a tour of example resources, organized by categories such as Algorithms and Analysis tools, expression resources, genome browsers (both Eukaryotic and Prokaryotic/Microbial) , Literature and text mining resources, and resources focused on nucleotides, proteins, pathways, disease and variation. This main discussion will then lead into a discussion of how to find resources with the free OpenHelix Resource Search Portal, followed by learning to use resources with OpenHelix tutorials, and a discussion of additional methods of learning about resources.

IMG extends capabilities

DOE JGI extended and updated the content of IMG and IMG/M recently as this linked press release shows (here is another), so today I’d like to just make a quick post to highlight that OpenHelix has a tutorial on IMG/M that is sponsored by JGI and thus free.

Metagenomics is a huge new field and IMG/M has some excellent tools and data!

Metagenomics making the big Times (as in NY)

Metagenomics, which is really a new area of study (barely this last decade) in comparison to most biological areas of research, is already making into the mainstream press. The New York Times has an article yesterday entitled “Bacteria thrive in the inner Elbow, No Harm Done” (you’ll need a free registration to read that). The article quotes from metagenomic studies that show that our inner elbows contain a unique microbiome of species even in comparison to our upper arm, though it goes a  more into metagenomic studies than just that. As the article states:

The research is part of the human microbiome project, microbiome meaning the entourage of all microbes that live in people.
The project is an ambitious government-financed endeavor to catalog the typical bacterial colonies that inhabit each niche in the human ecosystem.

That’d be this project. The article does a decent job of explaining why this project is helpful, but doesn’t really explain how this approach of metagenomics is different or how it’s done (in fact, it never says the word “metagenomics“). Oh well, can’t have everything.

For your edification: There is last year’s report “The New Science of Metagenomics” from the National Research Council (you can read free online, or purchase as a book. Also, of course there are at least two extensive databases of metagenomic data, IMG/M (free tutorial) and Camera.

FYI: The Third Annual JGI User Meeting is coming up

JGI_meet_imageHey, just a quick post to let you know about the upcoming user meeting for the Joint Genome Institute, which is occurring March 26-28th in Walnut Creek, CA. I’ve blogged about the JGI’s phenominal Integrated Microbial Genomes (IMG) resource & that will be discussed as well as LOTS of other interesting stuff. You can check out the meeting announcement & maybe meet some of the OpenHelix gang there!
