What you are seeing is likely the results of different settings. The FTDNA Chromosome browser has a few settings that are accessed by clicking on a drop down menu. GED match is almost infinitely adjustable by changing the settings on the page where you enter your kit numbers. As the math used is slightly different the start and stop values number of SNPs etc. may vary. If both browsers are set to the same settings, like 1.0 cM 500 SNPs, the results should match very closely. Mostly the GEDmatch browser is much more powerful and complex to use. ---------------------------------------------------------------------- From: M Robards <[email protected]> Subject: [AUTOSOMAL-DNA] Differing Info on Different Chromosome Browsers? I need some help reading the results on FTDNA's AND GedMatch's chromosome browsers for the same three people. I'm getting different readings from the two browsers. Does this mean I've done something horribly wrong in uploading their files from FTDNA? For instance, FTDNA says there is some matching segment(s) on Chromosome 16 between A and B and C. Yet GedMatch's browser shows no matching segments from B and C on A's. This is pretty confusing to me. melissa springer robards
Thank you so much, Sam. I did have the FTDNA browser set to show the minimum size segements, but not the one at Gedmatch. I'll see how it looks now. Hopefully I won't feel as dense this time :) melissa On Tue, Feb 14, 2012 at 6:42 AM, Sam Eaton <[email protected]> wrote: > What you are seeing is likely the results of different settings.
