NAME
bp_fast_load_gff.pl - Fast-load a Bio::DB::GFF database from GFF files.
SYNOPSIS
% bp_fast_load_gff.pl -d testdb dna1.fa dna2.fa features1.gff features2.gff ...DESCRIPTION
This script loads a Bio::DB::GFF database with the features contained in a list of GFF files and/or FASTA sequence files. You must use the exact variant of GFF described in Bio::DB::GFF. Various command-line options allow you to control which database to load and whether to allow an existing database to be overwritten.
This script is similar to load_gff.pl, but is much faster. However, it is hard-coded to use MySQL and probably only works on Unix platforms due to its reliance on pipes. See bp_load_gff.pl for an incremental loader that works with all databases supported by Bio::DB::GFF, and bp_bulk_load_gff.pl for a fast MySQL loader that supports all platforms.
NOTES
If the filename is given as "-" then the input is taken from standard input. Compressed files (.gz, .Z, .bz2) are automatically uncompressed.
FASTA format files are distinguished from GFF files by their filename extensions. Files ending in .fa, .fasta, .fast, .seq, .dna and their uppercase variants are treated as FASTA files. Everything else is treated as a GFF file. If you wish to load -fasta files from STDIN, then use the -f command-line swith with an argument of '-', as in
gunzip my_data.fa.gz | bp_fast_load_gff.pl -d test -f -The nature of the load requires that the database be on the local machine and that the indicated user have the "file" privilege to load the tables and have enough room in /usr/tmp (or whatever is specified by the \$TMPDIR environment variable), to hold the tables transiently. If your MySQL is version 3.22.6 and was compiled using the "load local file" option, then you may be able to load remote databases with local data using the --local option.
The adaptor used is dbi::mysqlopt. There is currently no way to change this.
COMMAND-LINE OPTIONS
Command-line options can be abbreviated to single-letter options. e.g. -d instead of --database.
--database <dsn> Mysql database name
--create Reinitialize/create data tables without asking
--local Try to load a remote database using local data.
--user Username to log in as
--fasta File or directory containing fasta files to load
--password Password to use for authenticationSEE ALSO
