This track shows the gaps in the 15 Sep 2017 Brassica napus/GCF_000686985.2_Bra_napus_v2.0 genome assembly.
Genome assembly procedures are covered in the NCBI
NCBI also provides
specific information about this assembly.
The definition of the gaps in this assembly is from the AGP file:
The NCBI document
AGP Specification describes the format of the AGP file.
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 has 32,639 gaps, with the following principal types of gaps:
- scaffold - gaps between scaffolds in chromosome assemblies (count: 32,639; size range: 10 - 462,331 bases)
