Bio::DB::CUTG(3)

NAME
Bio::DB::CUTG - for access to the Codon usage Database at http://www.kazusa.or.jp/codon.

SYNOPSIS
       use Bio::CodonUsage::Table;
       use Bio::DB::CUTG;

       my $db = Bio::DB::CUTG->new(-sp =>'Pan troglodytes');
       my $CUT = $db->get_request();

DESCRIPTION
This class retrieves and objectifies codon usage tables either from the CUTG web database . The idea is that you can initially retrieve a CUT from the web database, and write it to file in a way that can be read in later, using the Bio::CodonUsage::IO module.

For a web query, two parameters need to be specified: species(sp) and genetic code id (gc). The database is searched using regular expressions, therefore the full latin name must be given to specify the organism. If the species name is ambiguous the first CUT in the list is retrieved. Defaults are Homo sapiens and 1(standard genetic code). If you are retrieving CUTs from organisms using other genetic codes this needs to be put in as a parameter. Parameters can be entered in the constructor or in the get_web_request ()method. Allowable parameters are listed in the $QUERY_KEYS hash reference variable.

I intend at a later date to allow retrieval of multiple codon tables e.g., from a wildcard search.

  Support
Please direct usage questions or support issues to the mailing list:
