Parameters | Annotation Analysis | Category Variables

Category Variables
Specify character variables containing annotation categories. These variables are 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 this variable, then that row is excluded from the analysis for that set of annotation categories.
If these variables are not in the Input SAS Data Set, then you must specify them 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 single variable, or hold down Ctrl while left-clicking on multiple variables, from the Available Variables field.
*
