Ahh. Now I see what you're trying to do. You're taking the two pieces of the 15 cM segment, and deciding that if one was only 5 cM, then it wouldn't match anyone because the smaller side wouldn't reach the threshold that the company calls their minimum match.Yes. That's entirely possible and may be the reason ...

Jonathan: I don't understand your logic why a 6 cM limit means that the 15 cM wasn't born in some ancestor, but got longer. It's always a recombination that creates a new segment. Whether it or parts of it are filtered out by the company doesn't seem relevant to me because the filtering is only done in the DNA ...

Yinwang: The general method of imputation is to use samples from a population that best fit known values to fill in missing values. Imputed values will thus not catch many variants, and may result in non-matching segments with close relatives who should match and matching segments with people who shouldn’t ...

Cdxp: Yes, the parent company of Family Tree DNA is Gene by Gene, and their testing facility in Houston does both Family Tree DNA and MyHeritage. Gene by Gene changed recently to a new chip that allows for some custom selection of SNPs. Family Tree DNA and MyHeritage have different custom SNPs, with MyHeritage ...

Jarett, no, I wrote all the code myself. Double Matching is a technique I've never seen used before, so I'm discovering new ways to utilize it as I go.

Hi Jarett. My interest is more in the genealogical aspects of DNA testing I'm currently working hard to finish and release version 3 of DMT. www.doublematchtriangulator.com - I am not a genomics expert, but I'm learning.

mjashby: You make some good points. I think the GEDCOM export inaccuracies of Ancestry are their mistake, and if a connection is made with an online database, the connecting program in no way their mistake but attempt to do it correctly. If the online database stores things inappropriately, then conversion ...

ljonas1: It's too bad, but it looks like when they made the change, they also added security, so you can no longer download the file directly from a link any more. So the only way to get your raw VCF file now might be to contact Dante and ask them for it.

Justin. Yes it's dangerous if not done carefully. For shared trees like Family search, it would need to mimic the manual method a person would have to do it, and ask the exact questions that the online tree would ask. It should not allow new people to be added or people to be deleted without properly verifying ...

Keith: It wouldn't make sense for MacKiev to get rid of Sync. The only reason would be if Ancestry no longer let them do it. I hope Ancestry opens up their API to other developers in the future. It's a shame that only FTM and RootsMagic are given access to it.
