Data acquisition method

Perlegen 281K arrays、Affymetrix 500K arrays

Data analysis method

Common SNPs (MAF > 5%) were selected, and LDs (r2 values) between every SNP pairs within 300 kb were calculated. LD bins were collected so that every pairs within the bin shows r2 >0.8, by the greedy method of ldSELECT (Carson et al., AJHG 74, 106-120, 2004) after the program was modified so that it can handle haploid data.
