- The name is taken from the reference sequence used for mapping.
- The region of the
- The annotation name derived from the annotation (if there is additional information on the annotation, this is retained in this table as well).
- Target region length
- The length of the region.
- Target region length with coverage above...
- The length of the region that is covered by at least the Minimum coverage level provided in figure 17.1.
- Percentage with coverage above...
- The percentage of the positions in the region with coverage above the Minimum coverage level provided in figure 17.1.
- Read count
- Number of reads that cover this region. Note that reads that only cover the region partially are also included. Note that reads in over-lapping pairs are counted individually (see figures 17.6 and figure 17.7).
- Base count
- The number of bases in the reads that are covering the target region. Note that bases in overlapping pairs are counted only once (see figures 17.6 and figure 17.7).
- The GC content of the region.
- Min coverage
- The lowest coverage in the region.
- Max coverage
- The highest coverage in the region.
- Mean coverage
- The average coverage in the region.
- Median coverage
- The median coverage in the region.
- Zero coverage bases
- The number of positions with no coverage.
- Mean coverage (excluding zero coverage)
- The average coverage in the region, excluding any zero-coverage parts.
- Median coverage (excluding zero coverage)
- The median coverage in the region, excluding any zero-coverage parts.
Figure 17.6: A track list containing the target region coverage track and reads track. The target region coverage track has been opened from the track list and is shown in table view. Detailed information on each region is displayed. Only one paired read maps to the region selected.
Figure 17.7: The same data as shown in figure 17.6, but now the Disconnect paired reads option in the side-panel of the reads track has been ticked, so that the two reads in the paired read are shown disconnected.
In the shown figure, the coverage table is shown in split view with a track list. The coverage track has been opened from the track list by clicking once on the name found in the left side in the track list. When opening a read mapping in split view from a track list, the two views are linked, this means that when you click on an entry in the table, this position will be brought into focus in the track list.
