List,   I have in my recent blogposts found new ways to differentiate ancestry using Chromopainter (not Finestructure). The software provide the following numbers for further analysis:   * Proportions (that is admixture). * Number of shared segments (ChunkCounts) * Total shared (sum of shared segment sizes) (ChunkLenght) * Number of mutations, that is number of related but not identical haplotypes.   These numbers themself are interesting but with some simple arithmetic you can calculate the following:   * Segmentsize (Total shared segments divided by number of shared segments) * Divergence counts (Number of mutations divided by proportion).   I have by compared by real data and confirmed the following:   * Segmentsize increases with more closely related populations * Divergene counts decrease with more closely related populations.   As an example I have Lithuanians in the Fennoscandia Biographic Project both as project participants and as donor populations. These Lithuanians had the largest segmentsize and the lowest counts of mutations to the donor Lithuanians among the Fennoscandian participants.   This can open some interesting applications in f.ex detecting and differenciating minority ancestry, f.ex the Siberian mix in Fennoscandians including the Saamis appears to be old. However this would require some more testing using Sibierian and Native American controls and analysis but this method in Fennoscandian context it appears to be working. Saamis appears on average to have the largest mutational divergence to other European populations while Estonians appears to be the closest.   Anders
