## Description

This track shows locations of Sequence Tagged Site (STS) markers along the draft assembly. These markers have been mapped using either genetic mapping (Genethon, Marshfield, and deCODE maps), radiation hybridization mapping (Stanford, Whitehead RH, and GeneMap99 maps) or YAC mapping (the Whitehead YAC map) techniques.

Genetic map markers are shown in blue; radiation hybrid map markers are shown in black. When a marker maps to multiple positions in the genome, it is displayed in a lighter color.

## Using the Filter

This track has a filter that can be used to change the color or include/exclude the display of a dataset from an individual lab. This is helpful when many items are shown in the track display, especially when only some are relevant to the current task. The filter is located at the top of the track description page, which is accessed via the small button to the left of the track's graphical display or through the link on the track's control menu. To use the filter:

1. In the pulldown menu, select the map whose data you would like to highlight or exclude in the display. By default, the "All Genetic" option is selected.
2. Choose the color or display characteristic that will be used to highlight or include/exclude the filtered items. If "exclude" is chosen, the browser will not display data from the map selected in the pulldown list. If "include" is selected, the browser will display data only from the selected map.

When you have finished configuring the filter, click the Submit button.
