Map Contigs (ctgPos) Track Description
This track shows the locations of mouse contigs on the physical map.
The underlying data are derived from NCBI information
specific to this assembly. Although the NCBI data 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.
