Inquiry about depth of coverage and copy number variation

Question

[Chen]

Hi, everyone. I was wondering how we could distinguish depth of coverage and copy number variation when it comes to a specific gene when doing the analysis. Thanks:).

I don't understand your question. a DOC is the average depth , a CNV is a variation.

Thanks Pierre, I was actually thinking about the duplicate PCR reads and didn't explain it properly. I have found a post mentioning that question. Thank you!
