 <H2>Description</H2>
 <P>
 Bacterial artificial chromosomes (BACs) are a key part of many 
 large-scale sequencing projects.  A BAC typically consists of 25 - 350 kb of
 DNA.  During the early phase of a sequencing project, it is common
 to sequence a single read (approximately 500 bases) off each end of
 a large number of BACs.  Later on in the project, these BAC end reads
 can be mapped to the genome sequence.</P>
 <P>
 This track shows these mappings
 in cases where both ends could be mapped.  These BAC end pairs can
 be useful for validating the assembly over relatively long ranges.  In some
 cases, the BACs are useful biological reagents.  This track can also be
 used for determining which BAC contains a given gene, useful information
 for certain wet lab experiments.</P>
 <P>
 A valid pair of BAC end sequences must be
 at least 25 kb but no more than 350 kb away from each other. 
 The orientation of the first BAC end sequence must be &quot;+&quot; and
 the orientation of the second BAC end sequence must be &quot;-&quot;.</P>
 <P>
 The scoring scheme used for this annotation assigns 1000 to an alignment 
 when the BAC end pair aligns to only one location in the genome (after 
 filtering).  When a BAC end pair or clone aligns to multiple locations, the 
 score is calculated as 1500/(number of alignments).</P>
