 **What it does**
 
 Given a query set of genes from a larger background dataset, this tool
-evaluates the statistical over- or under-representation of Gene Ontology
-terms in the query set, using a two-tailed Fisher's exact test.
+evaluates the over- or under-representation of Gene Ontology terms in the
+query set, using the specified statistical test.
 
 The output contains a row for each GO term, with the following columns:
 
 1. count: the number of genes in the query set that are in this GO category
 2. representation: the percentage of this category's genes (from the background dataset) that appear in the query set
 3. ranking of this term, based on its representation ("1" is highest)
-4. Fisher probability of enrichment/depletion of this GO category in the query dataset
-5. GO term
+4. probability of depletion of this GO category in the query dataset
+5. probability of enrichment of this GO category in the query dataset
+6. GO term
