To run the tool:
Toolbox | Identify Candidate Genes () | Identify Mutated Genes ()
Select the gene track you wish to filter and click on the button labeled Next (see figure 25.5).
Next, select the variant track that should be used for comparison. An overlap has a simple definition - if the annotation used as input has at least one shared position with the other track, there is an overlap. The boundaries of the annotations do not need to match.
