Filter to Include Markers (applies to both data sets)

The Filter to Include Markers field is an optional parameter that enables you to subset both the Input SAS Data Set and Annotation SAS Data Set. Only those observations that meet all of the conditions specified in the field are included in the analysis.

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.
