Double Match Triangulator 2.9.4 - Fri, 21 Dec 2018

I’ve been working on DMT version 3.0 for the past few months and was hoping not to have to release anything before it’s ready.

Unfortunately, a few file format changes at some of the companies have caused DMT 2.1.1 to no longer recognize their files.

In October, I noted that Family Tree DNA made significant changes to the format of their Chromosome Browser Results file. But DMT was still able to handle it … until a month later when they made an additional change and added a space after the comma before the chromosome number. That broke DMT:

Also it was reported to me that MyHeritage Shared Segment files weren’t being recognized by DMT when including them as Folder B files.  As it turns out, that was such a dumb error of mine. In DMT, it was looking for “segements” in the file name instead of “segments”. If you changed, the file names to include the extra “e”, then they’d be recognized, but DMT wouldn’t read them because at reading time DMT was looking for “segments”. Catch-22.

The coup de gras was just this week when DMTs GEDmatch button no longer was able to handle the Segment Search report in GEDmatch Genesis. It turns out they added a checkbox to that report:

So at this point, DMT was having trouble with FTDNA, MyHeritage and GEDmatch files. I had created private versions (2.9.1 to 2.9.3) and sent them to people who reported these problems to me. But there was now enough needing fixing that an intermediate version for everyone was necessary. Thus, 2.9.4 is now available from the DMT homepage.

2.9.4 includes a few other fixes as well. But if you have not encountered problems with DMT, have not downloaded new FTDNA files, don’t use MyHeritage files or Tier 1 of GEDmatch Genesis, then there’s no need to upgrade and you can wait until 3.0 is released.
