CUB | R Documentation |
The function reads aligned sequences in a fasta file and estimates the codon usage bias for each sequence. Several methods exist to estimate CUB; so far, only the "Effective Number of Codons" (ENC) calculation is available.
CUB(file = NULL, sequence = NULL, method = "ENC")
file |
FASTA file in which aligned sequences are stored. |
sequence |
Alternatively, the result of seqinr::read.fasta. |
method |
The method used to compute CUB. "ENC": Effective Number of Codons, as described in Wright (1990). |
A named vector of CUB scores. Names correspond to sequence names in the dataset.
