Most of the statistics below have been calculated using only physical interactions—that is, excluding genetic interactions as well interactions predicted on the basis of computational methods. The exception to this is the iRefIndex Release Statistics table which includes all records.
In most cases we are counting interactions, not source database records.

Details of the current iRefIndex release being used by iRefWeb. Total records published is the total number of records that appear in the original version of the data distributed by the source database. Non-redundant protein-protein interactions are subsequently extracted from the data by the iRefIndex process. Total Interactions Found are the number of interactions left after processing (see the diagram at the top of this page for a clarification for how database records are related to interaction counts).
The iRefIndex consolidation process involved the identification of original records that contained protein-only interactors; the mapping of such proteins and interactions into the same representation system; the elimination of redundant representations; and further consolidation of splice variants through protein isoform canonicalization.
