My Heritage just released an improvement to their “labels for DNA Matches”. See their blogpost at: https://blog.myheritage.com/2021/12/labels-for-dna-matches-now-improved/
These are intended to help you organize your DNA Matches into groups. And, AND, AND … you can “Export entire DNA Match list” (click on the 3 vertical dots to the right of Filters and Sort by), and this spreadsheet will include a list of any labels associated with each Match.
This is a huge time saver for Triangulation. To the extent that we can identify our Matches as Paternal and Maternal, the Triangulation process becomes very simplified. Paternal side Matches will only Triangulate with other Paternal side Matches. NB: watch out for any Matches that may relate to you on both sides. For the vast bulk of our Matches, however, all we have to do is sort by side + Chr + Start and form groups.
If you’ve already done a lot of Triangulation, this will provide a good Quality Control check.
There are a few pesky details: you have to assign the dot labels*…; you have to merge the Match list with the segment list…; you have to analyze the start/stop locations and make a judgment call as to where the Triangulated Group starts and ends. But aside from these chores, the main headache of checking for Triangulation is gone. Having the effect of “phased data” means the shared segments on one side have to Triangulate only with other segments on that same side. *Clustering and Shared Matches will often indicate that we can assign “side” labels on a group basis. Triangulated Icons should always indicate the same “side”.
