Parameters | Genetics | Identity By Descent Threshold

Identity By Descent Threshold
Use the field/slider to specify a threshold for reporting pairs of samples.
Pairs of rows/samples that have IBD values greater than or equal to the specified proportion of alleles that are identical by descent will be reported in a data set with the suffix _prs appended.
Sample pairs will be notated using the names for the relationship similarity variables in the output data set; in other words either the user-specified Prefix or the default Prefix " IBD_ " with the sample row number appended.
If ID Variables are specified, their values will be appended to the prefix instead of the row number.
Note : If a value of 0 is entered, the output data set will not be created.
To Specify the Identity by Descent Threshold:
Make sure Identity by Descent is selected as the Relationship Matrix to Compute .
Tip : To change the scale of the slider, right-click on the slider and select Rescale Slider from the pop-up menu. Change the upper and/or lower boundaries in the window that appears, to rescale the slider and click OK .
