Correspondence Analysis of Codon Usage
CodonW is a programme designed to simplify the Multivariate analysis (correspondence analysis) of codon and amino acid usage. It also calculates standard indices of codon usage. It has both menu and command-line interfaces. It was written by John Peden in the lab of Paul Sharp, Dept of Genetics, University of Nottingham. John is working in human genetics and is currently employed as ProCardis database manager at the WTCHG in Oxford University
CodonW was written as part of my PhD thesis on Codon Usage and if you are interested in reading in more depth around codon usage a copy of my thesis can be downloaded from here (1.72Mb).
NB: I have extensively tested it and believe it to be bug free. If you find a bug or something confusing please email me and let me know (Don't forget to tell me the Operating System and to send me the input file that generated the error).
Binaries are available for the following operating systems.
2. Irix 6.5 (64 bit)
3. Solaris 2.6(solaris)
4. Win 32bit (NT/95/98/2000/XP) (No GUI; runs within a DOS emulation window)
5. MacOS X version, (No GUI and runs from MacOS Unix terminal/commandline)
6. Web access via PISE at the pasteur http://bioweb.pasteur.fr/seqanal/interfaces/codonw.html
