I am studying clusters of ortholog genes of four algae species. I created 10'000 clusters, and I have one single GO term describing each one of them. I have selected 2'000 clusters that I am interested in, and I want to know how their GO terms are associated. Therefore, I only have as input a list of 2'000 GO terms and I would like to have as output something like a hierarchical map or summary. Is there any software that I can use to analyze those GO terms?
