NAME
bp_meta_gff.pl - Get/set Bio::DB::GFF meta-data SYNOPSIS
# set the following meta data values % bp_meta_gff.pl -d testdb tag1=value1 tag2=value2 # get the indicated meta data value % bp_meta_gff.pl -d testdb tag1 tag2 DESCRIPTION
This script gets or sets metadata in a Bio::DB::GFF database. Not all adaptors support this operation! To set a series of tags, pass a set of tag=value pairs to the script. To get the contents of a series of tags, pass the bare tag names. The output from the get operation will be an easily parseable set of tag=value pairs, one per line. COMMAND-LINE OPTIONS Command-line options can be abbreviated to single-letter options. e.g. -d instead of --database. --database <dsn> Mysql database name (default dbi:mysql:test) --adaptor <adaptor> Mysql adaptor (default dbi::mysqlopt) --user <user> Username for mysql authentication --pass <password> Password for mysql authentication SEE ALSO
