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.
