Description
This track depicts gaps in the assembly.
Gaps are represented as black boxes in this track.
If the relative order and orientation of the fragments on either side
of the gap is supported by read pair data,
it is a bridged gap and a white line is drawn
through the black box representing the gap.
This assembly contains the following principal types of gaps:
- Fragment - gaps between the Whole Genome Shotgun contigs of a
supercontig. (In this context, a contig is a set of overlapping sequence
reads. A supercontig is a set of contigs ordered and oriented during the
Whole Genome Shotgun process using paired-end reads.)
These are represented by varying numbers of Ns in the assembly.
Fragment gap sizes are usually taken from read pair data.
- Contig - artifical 1,000 bp gaps between supercontigs to construct
the artifical chrUn chromosome.
