Filter to Include Windows

The Filter to Include Windows field is an optional parameter that enables you to filter the Input SAS Data Set (and Haplotype Frequency Data Set, if specified) to only include the windows that meet the criteria specified in the statement(s).

For example, to filter only diseased individuals from a data set containing a mixed population of diseased (sick) and healthy (healthy) individuals (as indicated in a column named DiseaseStatus), you could use the following simple WHERE expression:

WHERE DiseaseStatus = ‘sick’

Note: the word where has already been entered for you.
