This track displays the best single alignment of each of the mouse whole genome shotgun reads. It was computed in the same manner as the Blat Mouse track, but when a read aligned multiple places all the alignments are displayed in that track, while only the best alignment is displayed in this track. On occassion the alignment score may be equivalent in multiple places in which case all equivalent 'best' alignments are displayed.
This track is produced at UCSC from mouse sequence data provided by the Mouse Genome Sequencing Consortium.
