  1. |slope AB| is the absolute value of the change of a given nucleotide at a given position (relative to total coding sequence GC content) in archaea/bacteria; |slope E| is the corresponding slope in eukaryotes. Error is a measure of the average consequence of a change in a particular base at a particular codon position (for example, T1 is T at the first position, using a methodology based on [69].
