Source: Interaction data source. Total records: Total number of interaction records found in source. Protein-only interactors:Total number of interactions involving only protein interactors. PPI assigned to RIGID: Number of interactions where all protein interactors were assigned to a ROG. Percentage of column 3 is shown. Unique RIGIDs (interactions): Number of unique protein interactions and complexes (RIGID's) found in the data source (also expressed as a percentage of column 4).
