  • a The percentage of genes of a given function within a given functional category.

  • b The percentage of a particular functional category within the cluster versus the percentage of genes of that functional category within the genome as a whole.

  • c The P value represents the probability that the number of genes associated with a specific pathway/regulon occurs by chance.
