Binding of individual Ly49 receptors to single MHC class I molecules in the sequential selection simulations.

For each receptor triplet, the binding properties between the Ly49 receptors and the individual MHC class I allele used in each independent simulation was retrieved from the cases with the lowest RMS value (Table 1) in that same way as for the two step selection model (Table 3). Data from from all individual cases with the lowest RMS values are shown independently in table S2.针对每个受体三联体（receptor triplet），我们采用与两步选择模型（two step selection model，表3）相同的方法，从表1中均方根值（Root Mean Square, RMS）最低的案例里，提取各独立模拟中所用Ly49受体（Ly49 receptors）与对应MHC I类等位基因（MHC class I allele）之间的结合特性。所有均方根值最低的独立案例的数据均单独呈现于补充表S2（Table S2）中。
