3.10.9. Annotate Regions

This algorithm identifies variants that overlap features in the selected source. While adding an annotation source can also identify variants that are contained within features, additional logic is performed to match variants. This algorithm only performs the simple case of whether or not the position is equal to or contained within a region in the annotation source.


An annotation source to use for annotating the regions or variants.


Columns for the selected source. If multiple features match the variant then the results will be joined together in a list for each field. If a variant does not have an overlapping feature the fields will be filled in with missing values.
