Can Dna Files From Other Companies Be Uploaded Into Ancestrycom

Post a Comment

Somehow, I missed the proclamation that Family Tree Dna now accepts uploads from MyHeritage.

Other people may have missed a few announcements as well, or don't understand the options, then I've created a quick and piece of cake reference that shows which testing vendors' files can exist uploaded to which other vendors.

Why Transfer?

But then that everyone is on the same folio, if you lot test your autosomal DNA at ane vendor, Vendor A, some other vendors allow yous to download your raw data file from Vendor A and transfer your results to their company, Vendor B.  The transfer to Vendor B is either complimentary or lower cost than testing from scratch.  One site, GedMatch, is non a testing vendor, but is a contribution/subscription comparison site.

Vendor B so processes your DNA file that you imported from Vendor A, and your results are so included in the database of Vendor B, which ways that you lot can obtain your matches to other people in Vendor B's data base who tested there originally and others who have also transferred.  Y'all tin can as well avail yourself of any other tools that Vendor B provides to their customers.  Tools vary widely between companies.  For instance, Family Tree Deoxyribonucleic acid, GedMatch and 23andMe provide chromosome browsers, while Ancestry does not.  All three major vendors (Family Tree DNA, Ancestry and 23andMe) have developed unique offerings (of varying quality) to help their customers understand the messages that their unique DNA carries.

Ok, Who Loves Whom?

The vendors in the left cavalcade are the vendors performing the autosomal DNA tests. The vendor row (plus GedMatch) beyond the tiptop indicates who accepts upload transfers from whom, and which file versions. Please consider the notes below the chart.

(Chart updated September 28, 2017)

Please annotation that on August 9, 2017, 23and Me began processing on the Illumina GSA bit which is not compatible with before versions.  As of tardily September 2017, just GedMatch accepts their upload and but in their Genesis sandbox area, not the normal product matching expanse.  This is due to the pocket-sized overlap area with existing chips.  Y'all can read more almost the GSA fleck and its ramifications here

  • Family Tree DNA accepts uploads from both other major vendors (Ancestry and 23andMe) but the versions that are uniform with the chip used past FTDNA volition have more than matches at Family Tree DNA. 23andMe V3, Ancestry V1 and MyHeritage results utilize the same scrap and format equally FTDNA. 23andMe V4 and Beginnings V2 utilize unlike formats utilizing only about half of the common locations. Family unit Tree DNA withal allows free transfers and comparisons with other testers, merely since there are but about half of the same DNA locations in common with the FTDNA chip, matches will be fewer. Additional functions can be unlocked for a i fourth dimension $19 fee.
  • Neither Ancestry, 23andMe nor Genographic accept transfer information from whatever other vendors.
  • MyHeritage does take transfers, although that option is not piece of cake to find. I checked with a MyHeritage representative and they provided me with the following information:  "You can upload an autosomal DNA file from your profile folio on MyHeritage. To access your profile page, login to your MyHeritage account, and then click on your name which is displayed towards the top correct corner of the screen. Click on "My contour". On the profile folio y'all'll see a DNA tab, click on the tab and you'll see a link to upload a file."  MyHeritage has also indicated that they will be making ethnicity results available to individuals who transfer results into their system in May, 2017.
  • LivingDNA has simply released an ethnicity product and does not have DNA matching capability to other testers.  Living Deoxyribonucleic acid imputes DNA locations that they don't test, but the initial download but includes the DNA locations actually tested.
  • WeGene's website is in Chinese and they are not a significant player, but I did include them considering GedMatch accepts their files. WeGene's website indicates that they take 23andme uploads, but I am unable to decide which version or versions. Given that their terms and conditions and privacy and security data are not in English, I would be extremely hesitant before engaging in business organization. I would not exist comfy in trusting on online translation for this blazon of document. SNPedia reports that WeGene has data quality issues.
  • GedMatch is not a testing vendor, so has no entry in the left cavalcade, but does provide tools and accepts all versions of files from each vendor that provides files, to engagement, with the exception of the Genographic Projection.  GedMatch is gratis (contribution based) for many features, merely does have more advanced functions available for a $10 monthly subscription. The GedMatch Genesis platform is a sandbox expanse for files from vendors that cannot be put into production today due to matching and compatibility problems.
  • The Genographic Project tested their participants at the Family Tree Dna lab until November 2016, when they moved to the Helix platform, which performs an exome test using a different chip.
  • The Ancestry V2 bit began processing in May 2016.
  • The 23andMe V3 chip began processing in December 2010. The 23andMe V4 flake began processing in November 2013. Their V5 chip August 9, 2017.

Incompatible Files

Please be aware that vendors that accept different versions of other vendors files can simply work with the tested locations that are in the files generated by the testing vendors unless they use a technique called imputation.

For case, Family Tree DNA tests about 700,000 locations which are on the same chip every bit MyHeritage, 23andMe V3 and Beginnings V1. In the after 23andMe V4 examination, the earlier 23andMe V2 and the Beginnings V2 tests, only a portion of the aforementioned locations are tested.  The 23andMe V4 and Ancestry V2 chips simply exam about half of the file locations of the vendors who utilize the Illumina OmniExpress chip, but non the same locations as each other since both the Ancestry V2 and 23andMe V4 chips are custom. 23andMe and Ancestry both inverse their chips from the OmniExpress version and replaced genealogically relevant locations with medically relevant locations, creating a custom chip.

Update:  In Baronial 2017, 23andMe introduced their V5 scrap which has only about 20% overlap with previous chips.

I know this is confusing, so I've created the following chart for scrap and examination compatibility comparison.

(Chart updated Sept. 28, 2017)

You can easily see why the FTDNA, Ancestry V1, 23andMe V3 and MyHeritage tests are uniform with each other.  They all tested utilizing the aforementioned chip.  However, each vendor then applies their ain unique matching and ethnicity algorithms to customer results, so your results will vary with each vendor, fifty-fifty when comparing ethnicity predictions or matching the same two individuals to each other.

Apples to Apples to Imputation

It'south difficult for vendors to compare apples to apples with non-uniform files.

I wrote about imputation in the article about MyHeritage, here and also more generally, here. In a nutshell, imputation is a technique used to infer the DNA for locations a vendor doesn't test (or doesn't receive in a transfer file from another vendor) based on the location's neighboring DNA and DNA that is "ordinarily" passed together every bit a packet.

However, the imputed regions of Dna are not your Dna, and therefore don't carry your mutations, if any.

I created the post-obit diagram when writing the MyHeritage commodity to explicate the concept of imputation when comparing multiple vendors' files showing locations tested, overlap and imputed regions. You can click to enlarge the graphic.

Family Tree DNA has chosen not to utilize imputation for transfer files and only compares the bodily DNA locations tested and uploaded in vendor files, while MyHeritage has called to impute locations for incompatible files. Family Tree DNA produces fewer, but authentic matches for incompatible transfer files.  MyHeritage continues to take matching bug.

MyHeritage may be using imputation for all transfer files to equalize the files to a maximum location count for all vendor files. This is speculation on my part, only is speculation based on the differences in matches from known uniform file versions to known matches at the original vendor and and so at MyHeritage.

I compared matches to the same person at MyHeritage, GedMatch, Ancestry and Family Tree DNA. It appears that imputed matches do non consistently compare reliably. I'm not convinced imputation tin always work reliably for genetic genealogy, because we need our own DNA and mutations. Regardless, imputation is in its infancy today and due to the Illumina GSA chip replacing the OmniExpress chip, imputation will be widely used inside the industry shortly for backwards compatibility.

To date, two vendors are utilizing imputation. LivingDNA is using imputation with the GSA chip for ethnicity, and MyHeritage for DNA matching.

Summary

Your best results are going to exist to test on the platform that the vendor offers, because the vendor's match and ethnicity algorithms are optimized for their ain file formats and DNA locations tested.

That ways that if y'all are transferring an Ancestry V1 file, a 23andMe V3 file or a MyHeritage file, for example, to Family unit Tree DNA, your matches at Family Tree Dna will be the same as if you tested on the FTDNA platform.  Y'all do non demand to retest at Family Tree DNA.

However, if you are transferring an Ancestry V2 file or 23andMe V4 file, you will receive some matches, someplace between one quarter and half every bit compared to a examination run on the vendor's own chip. For people who can't be tested once more, that's certainly meliorate than nothing, and cross-chip matching generally picks upwardly the strongest matches because they tend to lucifer in multiple locations. For people who can retest, testing at Family Tree Deoxyribonucleic acid would garner more matches and ameliorate ethnicity results for those with 23andMe V2 and V4 tests as well as Beginnings V2 tests.

For admittedly best results, swim in all of the major Dna testing pools, test as many relatives equally possible, and test on the vendor'south Native chip to obtain the about matches.  After all, without sharing and matching, at that place is no genetic genealogy!
