Genome Graphs (http://genome.ucsc.edu/cgi-bin/hgGenome), a new tool accessible via the ‘Genome Graphs’ link on the GBD home page, can be used to display genome-wide data sets, for example, the results of genome-wide SNP association studies, linkage studies and homozygosity mapping. Using the Genome Graphs tool, it is possible to upload or import several sets of genome-wide data and display them simultaneously (Figure 1), then accomplish such tasks as restricting the display to only those regions that exceed a set significance threshold, displaying genes via the Gene Sorter that exist in areas where the data meet a given significance threshold, displaying an area of interest in the Genome Browser and calculating the correlation coefficient (R) among the data sets. Both public and personal data sets may be loaded into the tool, and the display can be configured to suit individual needs.
