Database Statistics. Statistics on the M5nr databases showing total number of source databases, IDs, sequences and other key annotations. We show the number of unique elements added by each database that is added to M5nr. Looking at identifiers, sequences, functional annotations and organisms. For each item (IDs, sequences, functions, organisms) there is a total and percent. The total represents the count of unique representations of that item. The total count is important because there is duplication of sequences, functional names, and organism names within each source database.
