How do I manage duplicate kits at GEDmatch?

+15 votes

If you tested with different labs and have more than one kit in GEDmatch then “You should have your preferred kit set to Public, and any identical kits (same person but from other testing companies) set to Research.  Leaving multiple identical kits set to Public clogs up everyones match lists and reduces the effectiveness of many of the tools (eg. Triangulation reports).”

Here are step by step instructions for how to change a duplicate kit to research mode:

Login to your GEDmatch account

Near the bottom left of the main page, click on “EDIT or DELETE your DNA resource profiles”

To the far right of your DNA kit (that you want to change to research mode), click on the SELECT button

Then at the bottom of the page click on the EDIT button.

Under Public/Private/Research change to Research

Then at the bottom click on the Save_Changes button
I changed it to research. I did not know I had to have only one public. Sorry about that. The reason I took the second test with FTDNA is because I thought the Ancestry test was not correct and was not showing cousns on both sides. By comparing both tests on Gedmatch I was able to prove that both tests were identical.

Harry, I had the same sense about the difference between the two testing companies, because the follow through of Ancestry re my 2nd test (a waste of money and time) seemed not to be handled well at all. But you now say that you've proven that the tests were "identical." What made you think that? It's so easy to make false conclusions, so I had to ask.
I do NOT have a duplicate kit on gedmatch, however on the gedmatch main page my daughters kit says it may be a duplicate and might need deleted? It is my daughter, not you know how I can fix this? Thank you

Peter, thanks for posting about this.  I have many, many matches (aarrggh!) that have three or more kits, all public, on Gedmatch.  Was just going through one of my GenomeMatePro files the other day combining a bunch of them . . .
