Dprime Upper Confidence Limit less than:

Use this field to specify a maximum acceptable upper confidence level for D’. Only those pairs of SNPs with an upper confidence level less than that specified here can be considered to display "historical evidence of recombination".

Note: Pairs that are either in strong LD or display historical evidence of recombination are considered "informative pairs."

To Specify a Maximum Acceptable D’ Upper Confidence Limit:

Type a value between 0 and 1 in the Dprime Upper Confidence Limit less than: field.
