Just wanted to make you aware of the S6881 panel at YSEQ which I created as a cheap way to fit likely or confirmed S6881 people into the S6881 tree. However I note Chris's tree has some extra SNPs. If it is possible to improve the panel I expect this can be done. 7 is the minimum SNPs for a panel, and I only have 7 and YSEQ weren't happy about the quality of one of them. On the other hand adding SNPs would make the test (currently $103) more expensive. A replacement strategy would be a way to go.
In time I would expect to see panels below the S6881 panel to address single name groups e.g. a Warburton panel, or a Graves panel based on their currently known singletons. The role of BIG Y is to do 1 or 2 to identify enough singletons, and then panels to fit the majority of people.
