Default Display The default view shows the S. pombe genome with mapping data of siRNA and chromatin modifications, for the wild-type organism. However, it is possible to surpress, or compress (dense) the display of this data, and it is also possible to display additional tracks showing the same data in a mutant background (clr4D - clr4 deletion ). Also shown in the default view is the genome position of annotated proteins, and the mapping of the probes used in this study.

Displaying Data Each data item is controlled by a button. Clicking on the name above the button provides information about the data being plotted and additional control over the display. Each button offers at least 3 choices:

• hide - do not display the track;
• dense - show the information in a compressed format (for the graphs this is a single bar with color intensity representing values);
• full - shows the entire graph or all possible genes/proteins. (note: full will not work if there is too much data to display (e.g. CDS for the entire chromosome.)

Navigation Within the browser one can zoom and center the display by clicking within the Base Position ruler at the top of the image. One can also zoom the display in/out by using the buttons at the top of the page. It is also possible to type in a specific chromosome or position range into the box labelled "position" (e.g. chr1 shows all of chromosome 1, while chr1:5000-10000 show chromosome 1 between base 5,000 and 10,000.

Searching It is possible to search for a particular gene by typeing its name into the box labelled "position". Searching is currently limited to gene/protein name. Searches are case insensitive, and are considered to have a wild card following them - thus searching for meu will match all names beginning with meu (e.g. meu1, meu22 etc).

Search examples: ura4 will immediately locate you to the Ura4 gene locus, and SPCC330 will provide a list of matching genes whose name begins with SPCC330.
