BP_LOAD_GFF(1)	      User Contributed Perl Documentation	BP_LOAD_GFF(1)

NAME
       bp_load_gff.pl - Load a Bio::DB::GFF database from GFF files.

SYNOPSIS
	 % bp_load_gff.pl -d testdb -u user -p pw
	    --dsn 'dbi:mysql:database=dmel_r5_1;host=myhost;port=myport'
	       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 uses the Bio::DB::GFF interface, and so works with all
       database adaptors currently supported by that module (MySQL, Oracle,
       PostgreSQL soon).  However, it is slow.	For faster loading, see the
       MySQL-specific bp_bulk_load_gff.pl and bp_fast_load_gff.pl scripts.

   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 -

       On the first load of a database, you will see a number of "unknown
       table" errors.  This is normal.

       About maxfeature: the default value is 100,000,000 bases.  If you have
       features that are close to or greater that 100Mb in length, then the
       value of maxfeature should be increased to 1,000,000,000, or another
       power of 10.

COMMAND-LINE OPTIONS
       Command-line options can be abbreviated to single-letter options.  e.g.
       -d instead of --database.

	  --dsn	    <dsn>	Data source (default dbi:mysql:test)
	  --adaptor <adaptor>	Schema adaptor (default dbi::mysqlopt)
	  --user    <user>	Username for mysql authentication
	  --pass    <password>	Password for mysql authentication
	  --fasta   <path>	Fasta file or directory containing fasta files for the DNA
	  --create		Force creation and initialization of database
	  --maxfeature		Set the value of the maximum feature size (default 100 Mb; must be a power of 10)
	  --group		A list of one or more tag names (comma or space separated)
				 to be used for grouping in the 9th column.
	  --upgrade		Upgrade existing database to current schema
	  --gff3_munge		Activate GFF3 name munging (see Bio::DB::GFF)
	  --quiet		No progress reports
