1.1. Two reference insertion variants can be reported at the same position
In regions where the evidence could support different insertions, it is possible for 2 reference variants to be reported at the insertion position, instead of one reference variant, as would be expected.
If this effect is observed in your data, we recommend carefully inspecting the corresponding area of the read mapping to evaluate the reported variants.
Two reference insertions at a given position will look something like this in a variant track:
- CLC Genomics Workbench 7.5 and up
- Biomedical Genomics Workbench 2.1 and up
- CLC Genomics Server 6.5 and up
