## Description

This track depicts gaps in the assembly. These gaps - with the exception of intractable heterochromatic gaps - will be closed during the finishing process.

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 known, it is a bridged gap and a white line is drawn through the black box representing the gap.

Gap locations were extracted from the sequence by looking for stretches of at least 25 consecutive N bases.

Gaps were considered to be one of these two types, based on length:

- Contig - gaps of size 50 Kb or fewer.
- Scaffold - gaps greater than 50 Kb in size.
