One need not spend light years traveling to a galaxy far, far away in search of free data-analysis tools. This Galaxy, the brainchild of the people at the Center for Comparative Genomics and Bioinformatics at Penn State University, contains an entire constellation of data-analysis tools that allow researchers to profile metagenomic samples, compare genomic annotations, and analyze multiple alignments, to name just a few of the tools’ capabilities. The website boasts that Galaxy “allows you to do analyses you cannot do anywhere else without the need to install or download anything,” and indeed, I was initially suspicious of “the catch.” The site is so sleekly designed that I initially thought Galaxy was a commercial tool that required purchasing. (Imagine my delight when I found out that it wasn’t!) With so much to explore, the best place to start is the Galaxy Wiki, complete with video tutorials.
