This track represents the super-contigs as assembled from the fragment contigs.
The locations were extracted from the Broad Institute delivered file assembly.agp
Broad Institute Horse Genome Project.
The genome has been sequenced to 6.8X coverage. See also
Broad Institute Assembly Statistics.
There are 55,316 contigs in the assembly containing 2,428,773,513 nucleotides.
The mean size of these contigs is 43,907 bases, with an N50 measurement of
6,246 contigs of size 112,381 bases or larger containing half of the sequence.
The smaller contigs have been assembled into two types of supercontigs.
73 of the supercontigs named scaffold_0 through scaffold_87 containing 2,242,897,370 nucleotides
comprise chromosome 1-31 and chromosome X.
The mean size of these supercontigs is 30,724,622 bases, with an N50 measurement
of 33 supercontigs of size 53,663,962 bases or larger containing half of the
There are also 9604 supercontigs named chrUn0001 through chrUn9604 containing 107,858,955 bases.
The UCSC genome browser combines these supercontigs together as an
artifical chromosome chrUn with 1,000 base gaps between these supercontigs.
This chrUn sequence is 117,461,955 bases, with artificial 1,000 base
gaps covering 9,603,000 bases.
