a Matrix highlights the SNP pairs with correlation larger than a certain threshold for a given SNP panel. The SNP involved most is marked by an arrow (Step A). b Correlations are considered within the corresponding SNP subset and a tagSNP is selected (Step B). c All SNPs associated with the tagSNP have been removed from the remaining ungrouped SNP panel and the next round of iteration starts with Step A. Iterations continue until no ungrouped SNP is left
