I have been using your variant annotation tool VAT and I have a question about what the definition is of startOverlap and endOverlap. I went through the example workflow and I have annotated another file, but I do not have any variants annotated with these types in my files. I went through your website but I could not find a listing of definitions for the terms. Thank you.
These features are annotated only for indels. Essentially, when a indels affects the START of a gene or the end of a gene, it is annotated as startOverlap and end Overlap respectively. You can find extensive documentation for VAT at vat.gersteinlab.org. Please click on "Documentation" tab. Please let me know if you have any more questions.
