Description

This track shows the locations of human contigs on the physical map. The underlying data is derived from the NCBI seq_contig.md file that accompanies this assembly. All contigs are "+" oriented in the assembly.

Methods

For human genome reference sequences dated April 2003 and later, the individual chromosome sequencing centers are responsible for preparing the assembly of their chromosomes in AGP format. The files provided by these centers are checked and validated at NCBI, and form the basis for the seq_contig.md file that defines the physical map contigs.
