## Description

This track shows locations of Sequence Tagged Site (STS) markers along the draft assembly.

## Method

These STSs have been mapped using either genetic mapping (Genethon and Marshfield maps), radiation hybridization mapping (Stanford, Whitehead RH, and GeneMap99 maps) or YAC mapping (the Whitehead YAC map) techniques. Prior to August 2001, this track also showed the approximate positions of fluorescent in situ hybridization (FISH) mapped clones. In August 2001 and later assemblies, the FISH clones are displayed in a separate track.

## Using the Filter

The track filter can be used to change the color or include/exclude a map data set within the track. This is helpful when many items are shown in the track display, especially when only some are relevant to the current task. 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 only data from the selected map.
3. When you have finished configuring the filter, click the Submit button.
