Comparing different measures of domain promiscuity. Comparison of the different measures of versatility showing that they are correlated with the number of occurrences of a domain. Data were obtained from Pfam (for details refer to methods). Each point represents a different domain. Left, correlation with the number of occurrences of a domain. Right, correlation with the number of immediate neighbours. N – number of occurrences, NCO – co-occurrences, NN – number of direct neighbours, NTRP – number of triplets. Spearman rank correlation coefficients between the different measures are given in the respective panels.
