42**What it does**
43
44This tool can be used to analyze the patterns of linkage disequilibrium
45(LD) between polymorphic sites in a locus.  SNPs are grouped based on the
46threshold level of LD as measured by r\ :sup:`2` (regardless of genomic
47position), and a representative "tag SNP" is reported for each group.
48The other SNPs in the group are in LD with the tag SNP, but not necessarily
49with each other.
50
51The underlying algorithm is the same as the one used in ldSelect (Carlson
52et al. 2004).  However, this tool is implemented to be much faster and more
53efficient than ldSelect.
54
55The input is a tabular file with genotype information for each individual
56at each SNP site, in exactly four columns: site ID, sample ID, and the
57two allele nucleotides.
