Result of a GObar analysis of human genes with AT-AC-U12 type splice sites. The result of a GObar analysis is an SVG (scalable vector graphics) image, with a red path signifying branches that are disproportionately over-represented in the gene list, as compared to the distribution of all the genes from the organism. Placing the mouse over a GO term pops-up a window in the figure, with information on the GO term and links to download data. The tool also allows searching for terms, as well as zooming in and out of the image. Table 2, which is a section of a table that appears in a pop-up window at the website at the end of the calculation, shows GO terms that are significantly enriched in the dataset. The numbers on each path depict the deviation over the expected count, this calculation is described in the text.
