## 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 contigs 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 only one type of gap:

- contig - gaps in the sequencing of the Whole Genome Shotgun contigs. These are undetermined bases represented by varying numbers of Ns in the assembly. Fragment gap sizes are usually taken from read pair data. This assembly contains 76,804 unique gaps covering a total of 19,144,420 bases in the sequence.

## Credits

The Dec. 2009 Haemonchus contortus (Barber Pole worm) draft assembly (Sanger Institute,WormBase WS210) was produced by the Wellcome Trust Sanger Institute sequencing center.
