Hi Andreas, No one appears on your match list that does not match or exceed the minimum match criteria at Family Tree DNA, which is currently 20cM total and 7cM for an individual segment. If someone does not match both criteria, they will not be on your match list and they will now show on the ICW list either. IF you match at or above that level, you can see your matching cM down to 1cM to any individual. The ICW page is just another way to see your matches. No one will appear on your ICW list that does not already appear on your match list.

Hi everyone, was just stumbling across a post on WikiTree forum on DNAGedcom being able to triangulate data from GEDmatch and FTDNA. Leaving GEDmatch out for this thread (I think the OP refers to the paid tier 1 option which gives access to the top 200 triangulated matches and downloading that screen result - please correct me if there is another way) I want to question that remark about FTDNA. My assumption is that ICW (which isn't triangulation, can't repeat that often enough as there are still people out there who don't understand the difference or that there is one to start with) means that it includes all those 1cM matches (and larger) that FTDNA reports as a minimum criteria. Can someone confirm this? That makes the ICW tool even more worrisome if it's true as it's not even clear if a triangulated segment of only 1cM (or 2cM for that matter) is indeed an ancestral segment, triangulation or not (I refer to various discussions we had here and on other email lists about this - no need to start that discussion again until we have more proof).

Thanks Roberta, I think this is what Jim also meant. It only shows matching segments down to 1cM for matches that qualify both the 7.7cM minimum segment length and 20cM total cM. That should be the correct statement. I'm outside and don't have the article in front of me but as the main statement of it is "looking at small segments less than 7 or at minimum 5cM is rubbish" it forgets that we only look at those smaller segments in the same way that FTDNA does. At least I do, that means first it must be a TG proven by 3 or more people with matching segments > 5cM (or better 7cM) and then I look at those in the group that don't match to some in the TG. So far I could always prove that the original, bigger segment was chopped into smaller parts for some people but clearly still within the borders of the original TG. Thanks everyone, I really love the wisdom of this mailing list!
