42 <H2>Description</H2>
43 <p>
44 gcai calculates codon adaptation index (CAI) for each gene. CAI is measure<br />
45 a of the relative adaptiveness of the codon usage of a gene towards the<br />
46 codon usage of highly expressed genes, ranging from 0 (no bias) to 1<br />
47 (maximum bias). CAI can be used as a 'universal' measure of codon usage<br />
48 bias as it is correlated with various gene features such as gene expression<br />
49 level, GC content, and GC skew.<br />
