bp_pairwise_kaks

NAME

bp_pairwise_kaks - calculate pairwise Ka,Ks for a set of sequences

VERSION

version 1.7.3

SYNOPSIS

bp_pairwise_kaks.PLS -i INPUT-cDNA [-f FORMAT] [-o OUTPUT] \
[--msa tcoffee|clustal] [--kaks yn00|codeml]

DESCRIPTION

This script will take as input a dataset of cDNA sequences, verify that they contain no stop codons, align them in protein space, project the alignment back into cDNA, and estimate the Ka (non-synonymous) and Ks (synonymous) substitutions based on the Maximum Likelihood method of Yang with the PAML package. Often there are specific specific parameters you want to run when you are computing Ka/Ks ratios so consider this script a starting point and do not rely it on for every situation.

OPTIONS

-i, --input

The input file with the cDNA sequences. Must have at least two sequences, and be in a format that Bio::SeqIO is capable to read. In addition, if Bio::SeqIO is inable to automatically identify the format, the -f option should be specified. Technically not an option, this is a required value.

-f, --format

Specify the format of INPUT-cDNA for Bio::SeqIO.

-o, --output

Specify the file for output. Defaults to STDOUT.

--msa

Program used for alignment, either clustalw or tcoffee. Defaults to clustalw.

--kaks

Program used for the Ka/Ks estimation, either codeml or yn00. Defaults to codeml.

-v, --verbose

Be verbose.

-h, --help

Print help text.

Support

Please direct usage questions or support issues to the mailing list: [email protected] rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.
