## Description

This track shows the locations of $organism contigs on the physical map. The underlying data is derived from the NCBI seq_contig.md file that accompanies this assembly. Although the NCBI file indicates the orientations of the contigs based on how they were assembled into the final sequence, all contigs in this track are oriented to the "+" strand.

Although this track primarily displays the positions of large clones from the mouse reference strain, C57BL/6J, it also shows smaller overlapping contigs from alternate strains included in the NCBI data.
