+## Coexpression Clusters

+The coexpression network can also be compartmentalized using algorithms into more manageable clusters. These can be
+accessed from the sequences directly as a table (![table icon](images/table_icon.png "table icon")), 
+network (![network icon](images/network_icon.png "network icon")), 
+profile comparison (![profile icon](images/profile_icon.png "profile icon")) and 
+heatmap (![heatmap icon](images/heatmap_icon.png "heatmap icon")).
+
+In CoNekT functional enrichment for clusters is pre-calculated and enrichment for phylostrata/clades. The former can 
+shed light on the function of the cluster's members including those which currently lack annotation. The latter hints
+at the point in time when this feature evolved. To pick up co-expression clusters of interest, a search function is 
+provided in the tools menu, under **Find enriched clusters**.

+After specifying parameters, the **Count** button can be clicked to find out how many clusters meet the current criteria.
+
+When looking for clusters enriched for **plant-type cell wall biogenesis** in *Arabidopsis thaliana*, leaving other options
+at their default values eight clusters are found. This included **Cluster_66** which contains CESA1 , CESA6 one of the cellulose 
+synthases and **Cluster_148** which contains Cellulose Synthase like proteins. The other genes, lacking functional 
+annotation, in these clusters would be good canditates to knock out and test the phenotype of mutants for defects in their
+roots.
