DOWNLOADS: THE OPEN SOURCE Y-DNA PROJECT

[HOME]

This is an open source project meaning that all pertinent files now in development will be linked to in time. More information and updates about the project can be found at the above link and at the facebook group, Open Y-Tree.

The following files are intended for use by developers for validation and use of the Open Y data. Note that FTDNA, YFull, and YBrowse retain full rights to their data. Downloads are permitted only for informational, not for commercial, purposes.

• The Open Y haplogroup child/parent database
  From this, paths and whole trees can be constructed. But it's the haplogroup structure only. Full haplogroups, with its SNP members, is presently available only at https://ysnp.info/subclades.html. Once the work on that is done, that database will appear here.
  
  
• SNP information extracted from YBrowse.org
  Includes the SNP positions on the Y chromosome, ancestral and derived SNP values, and their names, including all alternate names.
  
  
• CSV file of all multiple SNP names
  Labs and other entities register new SNP names at YBrowse.org. Although the problem now appears to be under control, there are thousands of SNPs having multiple names. The Open Y project uses the names having the lowest order numeric portion of the name. For example, S200 is used rather than L448, despite that the latter is the most-used version. These, of course, cannot be purged, but it's best that standardized usages be promoted. And note that there are duplicate representations of some SNP names. It's pointless to remove them here as they will be downloaded over again every day.
  
  
• FTDNA recurrent SNPs
  The data is space delimited. The first field is the SNP name followed by the haplogroups for which it's a member. For more details, see this discussion about the recurrent SNPs in FTDNA's database.
  
  
• YFull recurrent SNPs
  As above but for YFull. For more details, see this discussion about the recurrent SNPs in YFull's database.
  
  
• Longhand to shorthand haplogroup names
  This isn't a comprehenisve list. Included are only the longhand haplogroup names (i.e. A1b1) used by YFull. The second field is the preferred shorthand (SNP-based) names (i.e. A-PF1260). The conversion is essential to the Open Y project as its critical for lining up multiple databases. However, the list is very much open to discussion, even criticism. Any errors? Have I missed some? Should some be expunged? This is probably the only data file that is not automatically regenerated every night. It's "hand-crafted." :) Help me get it right.
  
  
• Simple script to parse a child/parent database.
  Explanation is included in the file.
  
  
• Open Y haplogroups with member SNPs
  This is a space-delimited file in the manner of: SNP Haplogroups. At this release, there are more than 100,000 haplogroups and more than 660,000 SNPs with more coming. This version includes all but about 2500 of the FTDNA and YFull redundundant. They need further parsing.
  
  
• Vertical haplogroup tree
  A zipped text-based vertical haplogroup (only) tree. Each line leads with tabs, one for each downstream generation. I've written a tool that creates an HTML horizontal tree from this format but the result is far too big for a browser. I'll see what I can do.
