Nucleotide Pair Frequencies

Statistics | Nucleotide Pair Frequencies

This command is visible only if the data consists of nucleotide sequences. There are two options available: one in which the nucleotide acid pairs are counted bidirectionally site-by-site for the two sequences (giving rise to 16 different nucleotide pairs), the other, in which the pairs are counted unidirectionally (10 nucleotide pairs). MEGA will compute the frequencies of these quantities for each sequence as well as an overall average. They will be displayed in a Text Editor domain by domain (if domains have been defined in Setup/Select Genes & Domains).
