CodonW Description

CodonW is a programme designed to simplify the Multivariate analysis (correspondence analysis) of codon and amino acid 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.The CodonW project 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.Here are some key features of "CodonW":· Written in ANSI compliant C· Menu driven· Extensive number of command line options· Genetic code independent · No limits on 1. number of sequences 2. sequence length· Calculates the codon usage indices1. CAI: Codon adaptation index2. Fop: Frequency of optimal codons3. Nc: Effective number of codons4. CBI: Codon Bias Index · Calculates amino acid indices1. GRAVY score2. Aromaticity· Calculates correspondence analysis of 1. Codon Usage2. RSCU (Relative synonymous codon usage)3. Amino acid usage· Correspondence analysis 1. can include/exclude codons/amino acids2. can generate detailed reports of trends3. attempts to identify optimal codons automatically4. can allow additional data sets to be added 5. records any number of trends· Calculates gene parameters1. Gene length2. GC, GC3s and codon position specific G+C 3. Dinucleotide composition (in all three codon frames)4. Amino acid usage5. Relative amino acid usage6. Codon usage7. Relative Synonymous codon usage· Can conceptually translates sequences to protein· Reformats sequence data· Human or machine readable output· Can concatenate genes (whilst preserving reading frame) to calculate1. overall codon usage2. GC content3. Dinucleotide composition · Generates tables of codon, amino acid, or RSCU usage· Can even help you learn the Genetic code.· and more
