Filter to Include Markers
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 based on values of variables in the annotation data set. Only those markers that meet all of the specified conditions are included, in both the annotation data set and the corresponding marker columns in the input data set.
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.
