Add information from overlapping variants
This will create a copy of the track used as input and add information from overlapping annotations or variants:
Toolbox | Add Information to Genes (
) | Add Information from Overlapping Variants (
)
First, select the track you wish to annotate and click Next. You can choose any kind of variant or annotation track as input. Next, select the track for overlap comparison, again you can choose any variant or annotation track.
The result of this tool is a new track with all the annotations from the input track and with additional information from the annotations that overlap from the other track. The requirement for being registered as an overlap is that parts of the annotations are overlapping, regardless of the strandedness of the annotations (note that this makes it unsuitable for comparing e.g. two gene tracks but great for annotating variants with overlapping genes or regulatory regions).
When running the "Annotate with overlap information" tool with a gene track as input and a variant track as parameter track, a new column describing the specific variant is added to the Track Table. The variant description also appears in the track tooltips when mousing over the individual variants.
