Category Variable
Specify a character variable containing annotation categories. This variable is often obtained from an ontology hierarchy like the Gene Ontology (GO) or from lists of pathways. Note the following:
If a row has a blank value for a variable, then that row is excluded from the analysis for that set of annotation categories.
If this variable is not in the Input SAS Data Set , then you must specify it in the Annotation SAS Data Set on the Annotation tab.
To Specify Category Variables:
The Available Variables field is populated with variables from the specified data set.
Highlight a variable from the Available Variables field.
