I am using the Cytoscape plugin ClueGo to perform functional enrichment for genes in a network. I’ve been able to implement this through command line using CyREST with python by selecting certain ontologies as reference set for the enrichment. I would like to now use a custom reference/background list to perform functional enrichment. I see that this can be done on Cytoscape by changing the reference set option to ‘Custom Reference Set’ and uploading a file.
