*The fraction of identical genotypes was computed for all two-way combinations of 109 RI strains. Those pairs of strains for which the percentage of shared genotypes was greater than 75% were flagged and one member of the pair was eliminated from the BXN set. Corresponding matrices for AXB-BXA, BXD, BXH and the complete BXN matrix are available online at www.nervenet.org/papers/bxn.html in text format.
