GO Enrichment of Network Clusters

In my previous post, I mentioned how I clustered the network we obtained at the end. For functional annotation gene ontology (GO) enrichment has been done on these clusters. There were 20 clusters and the HGNC names are obtained separately for each cluster and using DAVID functional annotation tool API, GO and pathway annotations are collected per cluster and these are saved separately. http://david.abcc.ncifcrf.gov/api.jsp?type=OFFICIAL_GENE_SYMBOL&tool=chartReport&annot=GOTERM_BP_FAT,GOTERM_CC_FAT,GOTERM_MF_FAT,BBID,BIOCARTA,KEGG_PATHWAY&ids=HGNC_NAME1,HGNC_NAME2,HGNC_NAME3,... Above URL was used to obtain chart report for some GO and pathways chart records.
