Codon Adaptation Index Calculator

Introduction: CAI (Codon Adaptation Index) is an effective measure of synonymous codon usage bias. It may give an approximate indication of the likely success of the heterologous gene expression. This online tool calculates CAI according to the relative synonymous codon usage of a reference sequence or existing expression host organisms.
