The relationship between N and NN for selected examples. A) Correlation between the number of occurrences (N) and number of neighbours (NN) for the methyltransferase domain (PF08241) and the Sushi domain (PF00084) (corrected for repeats, see Methods, DVI calculation). Each data point corresponds to the number of occurrences and the number of neighbours that a domain has in one genome. B) Correlation between the number of occurrences (N) and number of neighbours (NN) for selected domains. Each data point the corresponds to the number of occurrences and the number of neighbours that a domain has in one genome. Domain ID, description and DV I are given in the left upper corner of the respective graph. For a definition of DV I, see section "The domain versatility index".
