[QUOTE]Originally posted by xyyman: [QB] @ AstenB. Appreciate your input but ...man, your analogies stink. No dis-respect intended. I am not sure I agree. First off, the data produce are ONLY "letters" not "numbers". If it is repeated 5 times then that is 5 repeats. (eg ATTTAATTTAATTTAATTTAATTA here ATTTA is reoated 5 times. The software should be able to count the five) And keeping in mind STRs are really organized or linked SNPs that are repeated. So we are talking apples vs apples in this context. YDNA or autosomal DNA should NOT natter. The problem to overcome will be the "address/location" where the specific or STR of interest starts. That is why I asked the question above about RsXXXXX?. I assume there is a software to do that. The question is where does the first ATTTA start on a genome that have over several million bases/alleles/SNPs? Here is a quote from another website with people working on the project using TreeMix when it just came out. We can do our own analysis. Things are much more improved compared to when the Amarna data was released. I challenged Davidski to run TreeMix on some data to prove my point I was making. He accepted the challenged then came back a day a later and said he would not. And deleted prior comments leading up to it. He are some excerpts from a dialogue using TreeMix(this is Dienekes) Quote: "Zack said: 1. I ran TreeMix on the Reich et al Indian Cline dataset (alongwith CEU, Yoruba and Onge). And I found a 57% migration edge from the Onge to Yoruba. [sarcasm]Obviously, there was back-migration from India to Africa.[/sarcasm] 2. Further evidence for continent-wide Eurasian admixture in Africa that had been previously undetected due to ascertainment bias that neglected African variation 3. Using the HGDP San as outgroup there is a 63% migration edge from (Basque, Sardinian) to San 4. All joking aside, I would love to see you actually attempt this TreeMix run if you haven't already done so. Why, because sub-Saharan African cattle are by-and-large African maternally and Zebu paternally, so some group introduced Zebu cattle to Africa. 5. When you have Shorthorn cattle found in South West Ireland, North Africa and down the coast to Senegal and inland to the Central Sahel. 6. My analysis cited by Razib in this post was based on 166,770 SNPs. Following Joe Pickrell's proposal of using -k 1000 for 650K data, I have repeated the experiment with -k 250. The first migration edge added was again: (Basque,Sardinian)-to-Yoruba (64%) 7. The slight greater affinity of West Eurasians and Africans is caused by geographic proximity and some admixture events 8. So, I have hypothesized that modern humans were evolving in parts of Africa pre-100ka, especially in a "Green Sahara", slowly achieving anatomical modernity. The de-greening of the Sahara would have pushed some of them into other parts of Africa, as well as into the Near East, were we first find them c. 100ka. 9. Dienekes • 5 years ago - It does seem that Yoruba, Mandenka, and Bantu are shifted relative to San in a West Eurasian direction:" [/QB][/QUOTE]
