I sent this report out today with an attached spreadsheet. The Patriarch is my g-g-g grandfather. The atDNA results discussed are for four known descendants and all matches are against, one person, the latest descendent to get results. Default settings were used for Dr Pike's tool and FF Chromosome Browser was run from the user's page. I doubt that the specific values on the spreadsheet will be of any value to the group at large. I will send copies of the spreadsheet to any that are interested. Still, I do find the results interesting in regard to small matching segments. Sam ---------------------------------------------- Note, the spreadsheet is essentially the report. The rest is explanation and comment. I find the FYDNA user tools quite useful, though not as powerful as the tools at www.GEDmatch.com. The issue with the GEDmatch tools is that the GEDmatch tools require surrendering much more privacy than many people are comfortable with. Dr Pike also has some very good tools on his site including the tool that I used, http://www.math.mun.ca/~dapike/FF23utils/pair-comp.php Dr Pike's tools require "Raw Data" to use and with out users granting the administrator use of their passwords are impossible for an FTDNA FF administrator to use. As this project was basically started with 23andMe data and was in existence before it joined FTDNA, I had already been in trusted with the necessary passwords. Now, most genetic genealogists find atDNA matches of less than 10.0 cMs and 700 SNPs very difficult to work with as there are many false positives and even where the match is in fact Identical by Birth, finding the correct match at a genetic distance of 4-10 or more generations and the thousands to millions of possible matches is not really a researchable undertaking. Our project is totally different. Our paper trail is about as good as it is possible to get. We are also rock solid on yDNA matches. So, the FTDNA tools showed 16 out of 127 of MLP's matches with the other three descendants of our patriarch that Dr Pike's utility found. Please remember that only one of the 127 matches would have shown up at 23andMe, and in fact, only that one of these matches is actually useful for most genetic genealogy research. Also remember that it is possible that many of the matches shown by Dr Pike's tool may be false positives. I think that it would be very useful if FTDNA was able to come up with an administrator's tool kit much like Dr Pike's. I am stumbling along and trying to also create a few tools that I think might be useful as well. Sam Eaton
