Merge Variant Tracks
Merge Variant Tracks takes as input one or more variant tracks (
) from compatible genomes. The output is a variant track containing all variants from the inputs.
To run the tool, go to:
Tools | Utility Tools (
) | Tracks (
) | Merge Tracks (
) | Merge Variant Tracks (
)
The following options can be configured (figure 27.33):
- Do not collapse All variants are included in the output as they appear in the inputs, without collapsing duplicates.
- Collapse Duplicate variants are collapsed to a single variant in the output. Variants are considered duplicates if they define the same mutation.
- Collapse (zygosity-aware) Same as Collapse. Additionally, if the collapsed variant is homozygous, remaining variants in the same region are discarded.
- Annotate variants When checked, additional attributes are added to the output:
- Origin tracks The input tracks containing the variant.
- For collapsed variants, original attribute values are stored in new attributes, with names formed by appending the name of the origin track.
