42 <H2>Description</H2>
43 <p>
44 genc calculates the effective number of codons (ENC|Nc). ENC is a measure<br />
45 for species-independent codon usage bias. Some measures including CAI are<br />
46 species-dependent as optimal codons differ. ENC assigns a gene a number<br />
47 between 20 to 61 where 20 indicates that one codon is used for each amino<br />
48 acid and 61 indicates that each codon is used equally throughout the<br />
49 protein sequence.<br />
