Starting from the Ensembl Web Site:

To view BayGenomics gene tags on the Ensembl site, go to Ensembl. Select the Mouse Genome Server. If you are interested in the location of a specific sequence, you can use BLAST or SSAHA to view the location of your sequence on the mouse genome. You can also just browse a chromosome.

Once you reach the ContigView on Ensembl, select Manage Sources from the DAS sources menu located in the "Detailed view" section.

Clicking on Manage Sources will open a new window called Additional DAS sources. To add BayGenomics to the list of DAS sources, click the red Attach DAS button.

Type baygenomics.ucsf.edu/cgi-bin in the blank space listed in the "Other" category. Then, click on the red Show sources button.

Select BayGenomics by placing a check in the box next to it and click the red Attach DAS button. This will add BayGenomics to the list of DAS sources.

You will see a screen confirming that BayGenomics has been added. Click on the red Edit button to change some of the features of the BayGenomics track.

In order to see all the genetags that are available for the specific region in which you are interested, you must change the Max no of rows to display from 4 rows to Unlimited.

Click on the red Update button to confirm the changes. Then close the window by clicking on the red Close button in the upper right hand corner. Once the window is closed, refresh the Ensembl Contigview webpage. The BayGenomics gene traps located in that specific region of the genome will be displayed.

If you look at the list of DAS sources again, you will notice that BayGenomics has been added near the bottom of the list.
