CNV analysis with Daniel Howrigan

[@danielgladish2502]

Nice video! Two questions: 1) Why would one want to exclude CNAs that overlap specific regions? Improve computational speed? 2) What would be the justification for setting the % exclusion zone overlap? E.g. why would I set overlap threshold to 50% and not 75%? Thanks!
