From: Predicting genes for orphan metabolic activities using phylogenetic profiles
The average phylogenetic correlation between a target gene and all other network genes at a certain metabolic network distance. The standard deviation of the average correlation for all possible network gaps is represented by the error bars. The dashed line shows the background correlation, estimated by the average phylogenetic correlation between any metabolic and non-metabolic genes. The average phylogenetic correlation between two genes decreases monotonically with their separation in the network.
