OpenHelix offers free access to a handful of their tutorials on genomics and bioinformatics resources, including the UCSC Genome Browser, Seattle SNPs, Genome Variation Server, and the VISTA Comparative Genomics tools.

An international team led by Sarah Tishkoff, in collaboration with our own Scott Williams, and former CHGR member Jason Moore, published yesterday in Science the largest, most comprehensive characterization of genetic variation in over 100 different African populations.

A reader asked yesterday how you would merge data from two different files. For example, let's say you have a ped file with genotypes for individuals, and another file that had some other data for some of the individuals in the pedfile, like clinical or environmental covariates.

When you need to focus and get some serious writing done, it may be a good idea to ditch your word processor and go with plain text instead. Save all your formatting and spell-checking to do later in one step. I just tried this out on a review article I needed to write and found it much easier to concentrate without all of MS Word's squiggly underlining, autocorrecting, autoformatting, and fancy toolbar buttons begging to be clicked.

I saw a demonstration of this tool at the workshop on network analysis I announced last week. Genes2Networks draws from a large background network consisting of several experimentally verified mammalian protein interaction databases. It will take a list of genes you provide as seed genes and identify all interacting genes that fall on paths through the background network between them.

Amidst the fallout of an academic discussion over the worth of GWA studies followed by several gloomy and scathing articles in the popular press, came this paper in Nature Genetics. In summary, the investigators sequenced all the coding DNA on the X-chromosome in families affected with an evidently X-linked mental retardation phenotype.

I briefly mentioned "time" in the previously posted Linux command line cheat sheet, but I can't overstate its utility especially for ACCRE/Vampire users. The time command does exactly what it sounds like: it times exactly how long it takes to run anything at the command line. And it couldn't be easier to use.
