Any sequence of N's in the assembly is marked as a gap in this track.
The standard gap track only shows the gaps as annotated in the AGP file:
The NCBI document
AGP Specification describes the format of the AGP file.
Gaps are represented as black boxes in this track.
There is no information in this track about order or orientation
