I've put up a file at http://dl.dropbox.com/u/2733445/DYS446%3D15.csv It contains 56 x 56 = 3136 comparisons of GD and off-modal matches for 56 111-marker M222 haplotypes. The columns are A Surname B Kit number C Surname D Kit number E GD F Number of off-modal matches. The data is sorted on column A, then on column E. So for each haplotypes, it gives a comparison with all other haplotypes (including itself). Sandy
