Identity By State Threshold

Use the field/slider to specify a threshold for reporting pairs of samples.

Pairs of rows/samples that have IBS values greater than or equal to the specified proportion of alleles that are identical by state 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 "IBS_" 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 State Threshold:

8

Make sure Identity by State is selected as the Relationship Matrix to Compute.

Either type the desired number of partitions into the text field, or move the slider to the right or to the left to specify a value.

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.
