[i] (#) Number of annotated genes.

[ii] (abs) Absolute number of predicted promoter regions that were found near annotated genes.

[iii] (rel) Percentage of predicted promoter regions that were found near annotated genes.

[iv] (O) X-fold overrepresentation, i.e., number of predicted promoter predictions that were found near annotated genes divided by the number that would be expected to be located near these genes if the same number of posiitons were distributed randomly across the chromosome.

[v] Due to a small number of double scoring regions (a region is scored twice if it is supported by genes from different gene groups), the total number of annotation supported regions is not equal to the sum over the number of gene group-related annotation-supported promoter regions.
