Codon usage software

   
    This page contains software for the analysis of codon usage in DNA coding sequences.

    CodonR: R source code and perl scripts for calculating tAI and the S test for translational selection.

    CodonW: modified version of the popular program for codon usage analysis. This version was tested on Linux, and the modification relieves the restriction on Nc values larger than 61 (this is done for statistical reasons when performing the S test above).
