Codon frequency reconstruction

 
The approximation of 64 codon frequencies is shown here for 319 Bacteria species. Archaea type can be found here.

Four approaches to reconstruction of the dependence of a codon frequency from the genome G+C content
Each panel shows observed frequencies of a given codon in 319 Bacterial genomes (light blue dots); 1999 Heuristic model 1999 fitting (black unfilled dots); Updated heuristic model 2009 fitting (black filled dots); Polynomial order 3 least square fitting (red dotted line); Logistic regression fitting (green dotted line)
