Hi Terry, What kind of feedback are you looking for? I think the most interesting parts are how it shows some of your closest matches and how it makes maps. My suggestion would be to add a lot more text and explanations. What exactly are we looking at? What information do you want us to get from the output? Maybe some sort of zoom function with a time scale (matches/map within 500 years, then 1,000 years, etc. or some sort of arbitrary scale if you don't want to be so specific in your time predictions). For some kit numbers I get only very close matches, for other kit numbers I get mostly very distant matches (but I only know this because I know the names of the matches etc. ahead of time). Also, I don't see the value of featuring your STR branch codes so prominently. For predicting which SNPs to test, I don't see much value in the tool right now. A completely dumb method of starting at the top with M253, M26, M223 etc and working down to more specific SNPs will work fine and a Deep Clade test can be easily ordered at FTDNA, and anyone who is interested enough to use your tool will probably be interested enough to find someone like Diana or this email list or a haplogroup project and get a smarter recommendation. How important is it that your computed STR tree doesn't completely reproduce the actual Y-SNP tree? Has your I1 tree made any useful predictions that have been confirmed by the new Z-SNPs? If your tree doesn't reproduce our actual paternal history, maybe your tool can still be useful, but I think you should make it something like a super-Ysearch or super-Y-DNA-match list and not make your tree the focus of intention.

Hello Bernie Cullen, Have you been able to get any of those Z106+ hispanic guys to test the other Z series SNPs? Wil
