 ### 2.2 Group-wise functional enrichment
 
-Now we will perform functional enrichment analysis on each of the bigger clusters separately. Sometimes stringApp does not detect the clustered network as STRING network, so switch to the unclustered network and back to the clustered one. Now, select the menu **Apps → STRING Enrichment → Retrieve group-wise functional enrichment**. In the resulting dialog, keep the **Column for groups** set to **__mclCluster**, which is the column with the sluter numbers. Then, press **Advanced** to show the advanced options and set the **minimum group size** to **10**, in order to retrieve enrichment results only for clusters with at least 10 nodes. Press **OK** and the **STRING enrichment** table will be populated with several tables, one for each cluster (look at the bottom right, next to the *Node* and *Edge Table*). You can explore the results of each of them separately. Note that if you only see enriched DISEASES, you need to reset the filter by pressing the filter icon, choosing **Select all** for including all categories, and pressing **OK**.
