The Life and Death of a DNA Segment - Blog comment by jonathanb - 21 Aug 2019
... start and end points. So when I see "the 15 cM segment", I read "a 15 cM region of DNA, where various matches might share various overlapping bits within that region."
Suppose that the 15 cM segment was "born" by combining two segments that were each exactly 7.5 cM long, and suppose that you match someone on the first 7.0 cM of the 15 cM segment. I can't think of any ...

Determining VCF Accuracy - Blog entry by lkessler - 13 May 2019
... need this initially set this up. Wilhelm HO has good set of them included with his DNA Kit Studio. The positions of variants in your gVCF file should be marked as no-calls. Many of these variants are false, but we don’t want them to break a match. The positions of variants in your filtered VCF should be marked as having that variant. This will overwrite most of ...
