Can I Not Upload Dna to Familytreedna Anymore

Somehow, I missed the announcement that Family unit Tree DNA now accepts uploads from MyHeritage.

Other people may have missed a few announcements too, or don't sympathise the options, and so I've created a quick and easy reference that shows which testing vendors' files can be uploaded to which other vendors.

Why Transfer?

Just so that everyone is on the same page, if you test your autosomal DNA at one vendor, Vendor A, some other vendors allow y'all 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 free or lower cost than testing from scratch.  One site, GedMatch, is not a testing vendor, just is a contribution/subscription comparison site.

Vendor B then processes your DNA file that you imported from Vendor A, and your results are then included in the database of Vendor B, which means that yous can obtain your matches to other people in Vendor B's data base who tested there originally and others who accept also transferred.  You tin besides avail yourself of whatsoever other tools that Vendor B provides to their customers.  Tools vary widely between companies.  For example, Family Tree Dna, GedMatch and 23andMe provide chromosome browsers, while Beginnings does non.  All 3 major vendors (Family unit Tree Dna, Ancestry and 23andMe) have developed unique offerings (of varying quality) to assist their customers understand the letters that their unique Dna carries.

Ok, Who Loves Whom?

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

Please annotation that on Baronial 9, 2017, 23and Me began processing on the Illumina GSA scrap which is not compatible with earlier versions.  As of late September 2017, simply GedMatch accepts their upload and just in their Genesis sandbox expanse, not the normal production matching area.  This is due to the small overlap surface area with existing chips.  You tin read more about the GSA flake and its ramifications here

• Family Tree Deoxyribonucleic acid accepts uploads from both other major vendors (Ancestry and 23andMe) but the versions that are compatible with the chip used by FTDNA will have more matches at Family Tree DNA. 23andMe V3, Ancestry V1 and MyHeritage results utilise the same chip and format equally FTDNA. 23andMe V4 and Ancestry V2 utilize different formats utilizing only almost half of the common locations. Family unit Tree Dna still allows complimentary transfers and comparisons with other testers, but since there are only near one-half of the same DNA locations in mutual with the FTDNA chip, matches will be fewer. Additional functions can exist unlocked for a one time $19 fee.
• Neither Ancestry, 23andMe nor Genographic accept transfer data from any other vendors.
• MyHeritage does accept transfers, although that choice is not easy to find. I checked with a MyHeritage representative and they provided me with the following information:  "Y'all can upload an autosomal DNA file from your profile page on MyHeritage. To access your profile page, login to your MyHeritage account, then click on your name which is displayed towards the top right corner of the screen. Click on "My profile". On the profile page you'll run into a DNA tab, click on the tab and you'll encounter a link to upload a file."  MyHeritage has also indicated that they will be making ethnicity results bachelor to individuals who transfer results into their system in May, 2017.
• LivingDNA has just released an ethnicity production and does not have Deoxyribonucleic acid matching adequacy to other testers.  Living DNA imputes Dna locations that they don't test, just the initial download only includes the Dna locations really tested.
• WeGene's website is in Chinese and they are non a pregnant player, but I did include them considering GedMatch accepts their files. WeGene'south website indicates that they accept 23andme uploads, merely I am unable to determine which version or versions. Given that their terms and weather condition and privacy and security data are not in English language, I would be extremely hesitant earlier engaging in business. I would non be comfortable in trusting on online translation for this type of certificate. SNPedia reports that WeGene has information quality problems.
• GedMatch is not a testing vendor, so has no entry in the left column, only does provide tools and accepts all versions of files from each vendor that provides files, to date, with the exception of the Genographic Project.  GedMatch is gratis (contribution based) for many features, but does have more than 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 Deoxyribonucleic acid lab until November 2016, when they moved to the Helix platform, which performs an exome test using a different chip.
• The Ancestry V2 scrap began processing in May 2016.
• The 23andMe V3 scrap began processing in December 2010. The 23andMe V4 chip 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 just piece of work with the tested locations that are in the files generated by the testing vendors unless they apply a technique called imputation.

For example, Family Tree DNA tests most 700,000 locations which are on the same chip as MyHeritage, 23andMe V3 and Ancestry V1. In the later 23andMe V4 exam, the before 23andMe V2 and the Ancestry V2 tests, just a portion of the same locations are tested.  The 23andMe V4 and Ancestry V2 chips simply test most half of the file locations of the vendors who apply the Illumina OmniExpress scrap, simply not the same locations as each other since both the Beginnings V2 and 23andMe V4 fries are custom. 23andMe and Beginnings both changed their chips from the OmniExpress version and replaced genealogically relevant locations with medically relevant locations, creating a custom fleck.

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

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

(Chart updated Sept. 28, 2017)

You tin can easily come across why the FTDNA, Beginnings V1, 23andMe V3 and MyHeritage tests are compatible with each other.  They all tested utilizing the same flake.  Nevertheless, each vendor then applies their own unique matching and ethnicity algorithms to client results, and then your results will vary with each vendor, even when comparing ethnicity predictions or matching the same two individuals to each other.

Apples to Apples to Imputation

It's hard for vendors to compare apples to apples with not-uniform files.

I wrote about imputation in the article almost MyHeritage, hither and also more than 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'due south neighboring DNA and DNA that is "normally" passed together as a packet.

Nevertheless, the imputed regions of Deoxyribonucleic acid are not your Deoxyribonucleic acid, and therefore don't conduct your mutations, if any.

I created the following diagram when writing the MyHeritage commodity to explain the concept of imputation when comparing multiple vendors' files showing locations tested, overlap and imputed regions. Yous 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 unit Tree Dna produces fewer, only authentic matches for incompatible transfer files.  MyHeritage continues to take matching bug.

MyHeritage may exist 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, but is speculation based on the differences in matches from known uniform file versions to known matches at the original vendor and then at MyHeritage.

I compared matches to the same person at MyHeritage, GedMatch, Beginnings and Family Tree DNA. It appears that imputed matches do not consistently compare reliably. I'g not convinced imputation can ever work reliably for genetic genealogy, because we demand our own Deoxyribonucleic acid and mutations. Regardless, imputation is in its infancy today and due to the Illumina GSA chip replacing the OmniExpress chip, imputation will exist widely used inside the manufacture before long 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 be 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 means that if you 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 Deoxyribonucleic acid will be the aforementioned as if y'all tested on the FTDNA platform.  You practise not need to retest at Family Tree Dna.

However, if you are transferring an Beginnings V2 file or 23andMe V4 file, you will receive some matches, someplace betwixt one quarter and half as compared to a exam run on the vendor's own scrap. For people who can't be tested again, that's certainly ameliorate than zip, and cantankerous-chip matching by and large picks up the strongest matches because they tend to lucifer in multiple locations. For people who can retest, testing at Family Tree DNA would garner more matches and better ethnicity results for those with 23andMe V2 and V4 tests also as Beginnings V2 tests.

For admittedly best results, swim in all of the major DNA testing pools, examination as many relatives as possible, and examination on the vendor's Native chip to obtain the most matches.  Later on all, without sharing and matching, in that location is no genetic genealogy!
