Bio-Tools-CodonOptTable A codon quality check tool, it produces a Codon Optimization table to see the quality of each codon. The simplest way of depiction is to plot the codon usage frequency that can be found in common codon usage tables. A more elaborate way to depict the codon quality is to convert the codon usage frequency into relative adaptiveness values. In contrast to the codon usage frequency the relative adaptiveness takes into account the number of codons which code for the respective amino acid. We produces each codon frequency, Relative Synonymous Codons Uses and Relative Adaptiveness of a Codon that can help to calculate the Codon Adaptation Index (CAI) of a gene. We generate a Graph between RSCU & RAC for better analysis.
