Ancestral Family Tree DNA Testing / Re: Contacting matches on MyHeritage?
« on: Monday 31 December 18 19:19 GMT (UK)  »
Just tried again and it worked ;D so must have been a glitch after all.

Thanks I wouldn't have kept trying without the encouragement.

Fingers crossed I get a reply.

Thank you for letting us know. Glad it worked out.

I tried again but no joy so I tried a couple I know was there before Dec 1st and the message box appeared.
It may be because the match is only on MyHeritage since Dec 1st that the message function isn't working for him and therefore not for me either.

I'll try again later.

Be interested to know how you get on if you could keep us updated please.

B.

Otherwise, why take the tests at all?

I agree with this, but even then it can be hard work getting responses.

There again if no one put a tree up where would we be?

I have asked for this thread to be closed as unproductive now it has descended into people calling other forum members out.

To answer the question that others had not specifically asked Genetic Affairs questions, answering for myself my reasons are

1. I have detailed my concerns upthread and GA has already had the opportunity to answer them fully but did not.
2. I indicated upthread that I was not going to make use of GA so to continue asking questions about it could be seen as argumentative and disruptive.

I agree that it's a lot less useful than matching at a site with a chromosome browser. 

But most matches at Ancestry never upload anywhere else so this is a way of speeding up the process of finding which of your matches share 20cM or more with your other matches.  This info is already available if you want to go through hundreds of pages match by match.


I really am not trying to be difficult here but if Genetic Affairs is just telling you that you share 20+cM with bob, sue and mary without giving any indication what chromosomes its on then it could be false matching in that whilst you do share 20+cM with each of those people it could be a different 20+cM in each case but you would not know that unless you had the chromosome breakdown. (In other words you have made matches with three different ancestors to three different people and not one ancestor matching with three different people). That is why I think there "must" be more to this matching and Genetic Affairs must somehow be getting access to underlying data.


And just for the record I do accept I could be wrong on all this but it is not possible to tell from the Genetic Affairs website that I can see

We don't know that though.

I think it just goes through all of your mutual matches at whichever site and takes note of who matches whom, which is the same information that any of us can access at Ancestry. It doesn't need to access that at a chromosome level.


Well if it is not accessing data at the chromosome level and making matches there it is much less useful than matching at say Gedmatch, ftdna or MyHeritage all of which have chromosome browsers and if that is the case then why use Genetic Affairs at all ?

What is of more interest to me is how is this new company doing this. A major gripe people have with Ancestry is that it does not have a chromosome browser to interpret tree matches. Yet this new site must gain access to the raw data of results if they can tabulate matches the way they do. That being the case why can't we have access to the data the new website is obviously getting? Anyone fancy questioning Ancestry about this and whether a chromosome browser is on the horizon?

I don't think it is accessing the raw data.

I think what it is doing is going through and finding ALL the shared matches (i.e. two people who share more than 20cM) for you and putting this in a table.


I don't think that is the full picture though. The fuller picture is that they are matching specific matches on specific chromosomes to specific people i.e. going into greater detail that can only be achieved by accessing the underlying data to some extent (sorry if I have not explained that very well).

I have just emailed FTDNA to ask whether use of this site is consistent with their terms and conditions.


I'll be interested in what they say (yes I am a customer of theirs).


As it says on their home page "we will not share your DNA" which is surely what this new company is being allowed to do. I also read the privacy policy quickly and am not sure they should be allowing Genetic Affairs to operate on their site if they follow their own rules.

Observation


I have looked at the site (Genetic Affairs) and read the Roberta Estes blog a few times and from what I can make out you have to give your log in to Ancestry, ftDNA or wherever to a third party site (Genetic Affairs). That third party site then logs into your account and mines the information there on your account and those of people who match it. If I have got this right I am unhappy about it because

1. you are giving out your log in and password to a third party to use
2. the third party is accessing your data, well that's OK if you give them permission but it is also accessing the information of who you match with and who have not given their permission for third parties to access it.
3. I am not sure how sites like Ancestry, ftDNA etc can justify this (yes I know they will argue that it is the account holders giving their permission but that is not wholly true is it, see 2 above).

So on reflection I will not be using this facility.


Question

What is of more interest to me is how is this new company doing this. A major gripe people have with Ancestry is that it does not have a chromosome browser to interpret tree matches.
