This script converts a Family Tree DNA haplogroup or surname project Y chromosome STR haplotype table to a Fluxus Network Y-STR data (.ych) input file. The free Fluxus Network software generates median-joining networks which can be used for the phylogenetic analysis of a set of DNA haplotypes. Here is an example of a Family Tree DNA Haplogroup Project:
The Family Tree DNA Haplogroup G Project For an example of a median-joining network produced by the Fluxus Network software from a Family Tree DNA surname project, see here:
The Clan Donald R1a median-joining network, including the clan chiefs and the presumed descendants of Somerled, Norse/Scotish ancestor of the Lords of the Isles. Here are some famous examples of discoveries in archaeogenetics that were made using median-joining networks: The following paper: "A Y-Chromosome Signature of Hegemony in Gaelic Ireland" made use of median-joining network analysis to prove the historical existence of the well-known ancestor of many Irish septs, Niall of the Nine Hostages, High King of Ireland at Tara, circa 450 CE. This paper "The Genetic Legacy of the Mongols" used median-joining networks to prove that Genghis Khan was the direct patrilineal ancestor of over 8% of the population of Asia, and 1 out of 200 men on earth. Due to a limitation of 1 KB per haplotype in Fluxus Network, STRs are not named but numbered sequentially by column in the dataset. Fluxus Network is also currently limited to haplotypes with no more than 96 STRs.
