The External View panel allows you to bring up all the data about a region from the UCSC server, if it is an organism that UCSC curates. While you can access information on very large regions (spanning 10-15 genes), a smaller region or specific gene may return more data due to more details being available. As a caution, the To use ENSEMBL you must have a fairly zoomed in picture (<100,000 bp) and it must be a species that ENSEMBL curates. The same is true for UCSC, although it can handle slightly larger regions of the chromosome. A smaller region or specific gene may return more data due to more details being available.

The larger the region in the inquiry, the slower it will be to load the information. |
Every time you move to a new area, you will need to click the update button (red box). Although the view is not interactive, you can get interesting details about a gene/region, including cross species comparisons, mapped ESTs, SNPs, and/or repeated sequence data, when available.
