# Gene Ontology (GO) Enrichment

With the *GO Enrichment* feature in Partek Genomics Suite, you can take a list of significantly expressed genes/transcripts and find GO terms that are significantly enriched within the list. For a detailed introduction to GO Enrichment, refer to the [GO Enrichment User Guide](/partek-genomics-suite/tutorials/rna-seq-analysis/gene-ontology-go-enrichment.md) (**Help > On-line Tutorials > User Guides**).

* Select the **Diff\_Exp\_and\_Alt\_Splice** spreadsheet from the spreadsheet tree
* Select **Gene Set Analysis** in the *Biological Interpretation* section of the *RNA-Seq* workflow (Figure 1)

A *GO-Enrichment* spreadsheet, as well as a browser (Figure 6), will be generated with the enrichment score shown for each GO term. Browse through the results to find a functional group of interest by examining the enrichment scores. The higher the enrichment score, the more over represented this functional group is in the input gene list. Alternatively, you may use the Interactive filter on the GO-Enrichment spreadsheet to identify functional groups that have low p-values and perhaps a higher percentage of genes in the group that are present.
