 <em>bigWig</em> - The bigWig format is best for displaying continuous value plot data, such as 
 read depths from short read sequencing projects or levels of conservation observed in a 
 multiple-species alignment. A bigWig file contains a list of chromosome segments, each of which is 
 associated with a floating point value. When graphed, the segments may appear as a big 
 &quot;wiggle&quot;. Although each bigWig file can contain only a single value for any given base, 
 bigWig tracks are often combined into &quot;container multiWig&quot; or &quot;compositeTrack 
 on&quot; tagged tracks. For information on creating and configuring bigWig tracks, see the 
 <a href="bigWig.html">bigWig Track Format</a> help page.</p>
 <p>
 <em>bigBed</em> - BigBed files are binary indexed versions of Browser Extensible Data 
 (<a href="../../FAQ/FAQformat.html#format1">BED</a>) files.  BED format is useful for associating a 
 name and (optionally) a color and a score with one or more related regions on the same chromosome, 
 such as all the exons of a gene. See the <a href="bigBed.html">bigBed Track Format</a> help page for
 information on creating and configuring bigBed tracks.</p>
