What's my terminal SNP?

A user in Spain reported reCAPTCHA issues. The problem was that Google changed the behaviour of its reCAPTCHA validation server, without issuing a corresponding change to its reCAPTCHA library. I've implemented a proposed workaround, while we wait for official guidance from Google.

Apologies for the unplanned downtime. It always seems to happen, for reasons beyond my control, while I am travelling or celebrating my birthday. Things should now be operational again.

5 January 2018

There will be some webserver maintenance this week. I don't expect lengthy disruptions. If there are, I'll give maintenance status updates via @MorleyDNA.

There were some website outages over the last week. It was an issue with my web host. I'll be working this month to move this service to a different server.

Is the "I'm not a robot" button not working for you? Try enabling third-party cookies. This seems to be a recent development.

MorleyDNA.com's web hosting plan is being upgraded. Consequently, there may be service disruptions over the next 72 hours.

Latest update.

8 November 2013

An update, in advance of the 2013 Family Tree DNA Genetic Genealogy conference. Over 2200 Geno 2.0 kits and over 7300 non-Geno kits.

When linking to these phylogenies, please link to https://ytree.morleydna.com/experimental-phylogeny (a list of all versions), rather than any particular PDF document. This way, people will not inadvertently use older versions.

7 September 2013

Another new version of the experimental phylogeny has been released. In addition to the almost 2000 Geno 2.0 kits (coloured blue), this report also incorporates several thousand non-Geno kits (coloured magenta). For the same reasons as below, the classifier still uses the 26 July 2013 phylogeny.

8 August 2013

A new version of the experimental phylogeny was released today. It features over 1850 Geno kits. It is the first version of this report to fill in gaps using select non-Geno data. Some of these non-Geno SNPs will be private. Others will turn out to be further upstream, only for the moment appearing to be private because they haven't been widely tested yet.

The new version also features corrections to some of the discrepancies noted in the 26 July version.

I have made some changes to the data structure underlying my experimental phylogeny. Until I make the corresponding changes to my predictor, its experimental predictions will continue to be based on the 26 July 2013 phylogeny.

As a demonstration of this software's versatility, the same algorithm used to process the Geno data was used to generate a phylogeny from the two-sample Full Genomes demo data.

By request, this and future versions of my phylogeny will be accompanied by a CSV summary file giving kit counts and SNP counts for each node.

Finally, at the end of last month I produced an automated report showing discrepancies and gaps in the ISOGG tree and SNP database.

Thank you for your interest in this project!

This project was launched on 16 July 2013 and since then it has gone very mildly viral. I'd like to temper some of the excitement directed towards the first version of my experimental Y-tree. Please don't overlook the "experimental" nature of this tree.

This project should be regarded as informative rather than authoritative. As I wrote in my announcement, it's not perfect, but it's a start.

Data Formats

Two main formats are supported:

FTDNA format.

Example:

M343+, L21+, DF13+, DF23+, M222-

For this option, the calls must be comma-separated. This is the format

Family Tree DNA uses in its projects' Y-SNP reports. It has been pointed out that the SNP list on the myFTDNA "Y-DNA Haplotree & SNPs" report is not comma-separated. We're experimenting with a workaround to accommodate this variant format. You'll get more comprehensive results if you join a public FTDNA project and use the data from that project's Y-SNP report (because the myFTDNA report only lists SNPs that FTDNA offers à la carte).

Full Genomes demo format.
The three-line header is optional. Partial headers may cause issues. Multi-named SNPs are accepted. Example:
```
PF6242  /  M343,+
S145  /  M529  /  L21,+
CTS241  /  S521  /  DF13,+
S193  /  DF23,+
USP9Y+3636  /  PAGE84  /  M222,-
```
Note: This is the format of Full Genomes Corp.'s demo datasets.

Documentation and discussion

Forthcoming. For now, see here for some details on notation.

The 8 November 2013 version of this phylogeny has attributes not yet supported by the classifier. So the classifier still uses the 26 July 2013 version of the phylogeny as its experimental tree.
See previous versions of this phylogeny, and other related documents.
