[index.html UTGB Toolkit] - BED Track

= BED Track

BED track is for displaying UCSC's [http://genome.ucsc.edu/FAQ/FAQformat#format1 BED format] data. To create a BED track, add the following XML fragment to your (project folder)/src/main/webapp/view/default-view.xml file (see also [customize.html How to customize browser contents]). Do not foget to set your BED file path to the {b|fileName} property:

<code>
<track className="org.utgenome.gwt.utgb.client.track.lib.BEDTrack" name="BED Track" pack="true">
  <property key="type">image</property>
  <property key="leftMargin">100</property>
  <property key="trackBaseURL">utgb-core/BEDViewer</property>
  <!-- this track reads BED data from db/sample.bed -->
  <property key="fileName">db/sample.bed</property>
</track>
</code>

== Create Indexes for Faster Data Browsing

Since utgb-shell-1.2.4, {b|utgb import} commands is available for creating database indexes (SQLite DB) of BED data. To create an SQLite index of your BED data, say db/reads.bed, type the following commands: 

<code>
> utgb import -t bed db/reads.bed
</code>

The SQLite index will be generated as db/reads.bed.sqlite file. When some SQLite DB file (suffixed with .sqlite) is found for the BED data, BEDTrack issues database queries to reads.bed.sqlite file, instead of reading reads.bed file.
